Testimonials + Before and After

“I picked up a new pistol at a gun show that had a horrible trigger, and I was incredibly disappointed. But Bart, the gunsmith at the Centennial Gun Club, did an amazing “trigger job” on it and it now feels as clean and crisp (if not better) than the trigger on my Kimber. Thanks Bart!!!”


HISTORYThis is an old (1981) LT 20 gauge 1100 whose receiver had been terribly scratched, worn, and abused…..Bart first skillfully removed all signs of scratches and abuse, but attempts to restore the factory blue failed twice…..the receiver had been overheated during the assembly of the mag tube (silver solder) when first manufactured… it would not take a uniform blue that looked good…..and since Bart refused to give this customer something that he was not proud of, Bart went the extra mile and had the receiver sealed with CeraKote (Premium Elite midnight blue) and the results are beautiful! From a timing and satisfaction perspective, Bart bent over backwards to make sure I was happy with the work and the turnaround time.


This is a customer from your great Centennial Gun Club I have recently found interest in firearms last year but unfortunately in my family I am the 1st to explore the nature of guns and firearm laws in general and as you can imagine this can be very uneasy to talk to salesman and experts in the field since I am a minority and I have found to be treated differently although I’m proud to be a American and look at everyone to be human first which unfortunately isn’t the case by visiting different gun ranges and stores I’m writing this email just to say thank you to your staff and gun smiths for making me feel like a person first and foremost long story short I will continue to shop and use your gun range versus others for that simple fact alone I may not be rich since I’m your average hard working American but I appreciate the small things in life that matter most to me in short.

Bart, As I expected, you did an outstanding job with the Colt 9mm Combat Commander I dropped off. I had no idea why it would be having cycling issues. Since you completed the work we’ve shot over 250 rounds with it. It’s now accurate AND reliable. Thanks for helping me with hard to fix guns over the years. I always know where to bring them.

I have asked Bart and his team to replace the factory sights on a Springfield Armory XD(m) and two XD40 SCs with Trijicon HD sights. As defense pistols, I had wanted night sights with a wider rear notch and high visibility front post with an orange dot. The team completed the job swiftly and, in my range test today, the sights were spot on for windage and elevation. Now Bart has done a variety of superb gunsmithing jobs for me over the last several years; I am completely satisfied with his latest work.

I have taken a number of different firearms into to Bart and have received excellent advice, recommendations, and always superb workmanship by him and his team. He has replaced sights, glass-bedded three rifle actions for me, inspected service rifles and kept me successfully shooting across a range of disciplines for more than five years. Legacy Gunsmithing is my “Go-To” first stop for any firearms questions and I trust them completely. A hearty thanks and well-done for this recent job…it will certainly not be the last!


I just wanted to express my special note of appreciation to Jacy for upgrading my new Sig MCX 556 Rattler with Romeo and Juliette red dot optics and other accessories. I am very pleased with this Rattler purchase at the Centennial Gun Club and Jacy was also very helpful in my making these important purchase decisions. I plan on making further upgrades and purchases in the near future, and will be looking forward to Jacy’s expertise in this regard.

Have been a customer of Legacy Gunsmithing for a few years and trust them completely with my firearms. Among other things, Bart and his team restored a cherished Browning Hi Power to magnificence.

More recently, I asked Bart to fit a barrel to my Rizzini/Sigarms Aurora shotgun. The gun is several years old and the replacement barrel was different enough to require significant fitting.

Bart did an amazing job. It locks up tight as a bank vault and ejects shells in a parallel arc. His work and attention to detail are both second to none. Fitting shotgun barrels seems to be a declining commodity, but Bart knows his craft.

I completely recommend Bart Miller and Legacy Gunsmithing for all types of repairs and projects, but particularly for those heirloom guns you want to be perfect.

I want to thank you for the outstanding, and I mean outstanding, job you did for me finishing the stock work on my custom model 98 Mauser, as well as in repairing the 60-year old double set trigger mechanism on my Wilbur Hauck single shot rifle.  Because there are only 148 known Hauck single shot rifles in existence, there are precious few who even know his name.  When my rifle began developing trigger issues, I brought it to you because of your reputation in dealing with high quality weapons and performing top-notch work.  Clearly you exceeded my expectations.
In my book you definitely deserve the title of master gunsmith as you are many grades above and beyond the majority of guys who hang out a shingle claiming to know their way around sophisticated gunsmithing but in reality know very little.

I wanted to let you and your staff know how much I appreciated the fine excellent and professional service and expertise all of you showed me when I gave you four of my 1911 handguns to check over, clean and work on one with a trigger issue. I shot all of them and they performed great, no issues at all.

I appreciated the fast turn a round on my carry Gun as well. I shot it in the IDPA match this week and it was a pleasure to have no malfunctions and totally enjoyed it once again.

Thanks for being at the club and there for us.

I have used four Gunsmith’s over the past 40+ years, in three different locations in the U.S. Bart Miller is the best Gunsmith I have ever relied upon. Specifically, the quality of work, quick turn around time, superb skills and customer service, and reasonable costs, allow me to say Legacy Gun Smith is the best. We are fortunate to have Bart and his team at Centennial Gun Club. Most recently, I took a completely locked up pistol with a round in the chamber to Bart for advise, because I was certain I needed to return this new pistol to the manufacturer. Bart calmly took the pistol, and in about 10 minutes, presented me with a defective bullet, and thus a perfectly functioning pistol…free of charge. I have used Bart and his team for multiple upgrades and am totally satisfied with their level of perfection.


I wanted to tell you about my recent experience with selling two revolvers to you at the Centennial Gun Club. I had seen you “advertising” at the club and from emails that I had received. I had two revolvers that I did not use and did not want to keep so I brought them over to the club and spoke to Lucas. He explained to me in detail how the process worked and that he would need about 30 minutes to review the revolvers and obtain a price.

When I came back he had a price much higher than I had expected…which came as a very pleasant surprise. I agreed to the price and the transaction was very simple, quick and seamless. Your team handled all of the needed paperwork which was even better.

Thank you for a great experience. Should I have other firearms that I wish to sell I will not hesitate to use your service or recommend you to others who may be in the same situation.

Thanks again.


I cannot express how thankful I am for the work Bart did on repairing my dad old Winchester Model 70, 30-06. My dad had passed away in late 2020 after a hard-fought battle with cancer. His old Winchester was what my dad had taught me how to shoot with and had left it to me to pass down to my son. I cannot count the number of memories I have hunting with my dad, with his rifle by his side. His rifle was the one I used to harvest my first deer and my first elk.

A week after he passed away, a relative picked up his rifle and had taken it elk hunting. I had reservations about this, and I had offered the use of any of my personal rifles, including of the exact same model but they refused, saying that he had been looking forward to that hunt and had offered the use of his rifle as he knew it would most likely be his last hunting season.

When the rifle was finally returned, it was broken in half. It had been dropped and snapped at the wrist of the stock. I understand accidents happen, but the grief was almost unbearable as I was still mourning his death. I had taken the rifle to several gun smiths around town, and all of them had told me that the rifle was beyond repair, and I was better off turning it into wither a “wall hanger” or buying a new stock for it, but I couldn’t bring myself to go with either of those options.

Many of the memories I have hunting and shooting my dad and his rifle were etched in the character of that stock. From the wear on the finish from years carrying it in a scabbard while riding our horses through the mountains and hills we hunted to the scratches left behind on the wood while moving through heavy brush. He was excited that I would teach my son to hunt and shoot with that rifle as well as share with my son similar memories he had shared with me.

When I had taken the rifle to Bart and his team, they noted to me the severity of the damage and that there could be a risk of the rifle breaking again due to the recoil. Although Bart had made this clear, he was confident in their abilities to repair and conserve the rifle. On what would have been my dad’s 72nd birthday, six months after he passed away, I got a call from Bart asking me to come in and look at the work he had done to my dad’s rifle. I hurried to his shop and upon examining the rifle, I could not tell that it had ever been broken. The detail of the work Bart had done left the rifle looking as it was prior to it being broken. He completely conserved the rifle and thus all the memories I had shared with my dad. Even going as far as to fix the checkering that had been smashed during the impact of the fall that had caused the break. Every grain of wood is in place and all the character of the stock there. I cannot see with my naked eye any remnant of the break.

Bart’s work is solid and the rifle is completely functional, leaving me with zero worries about the pressure of the recoil causing the break to reappear. I cannot thank him and his team enough for the attention to detail and quality of work. The quality of craftsmanship is beyond anything I had ever expected.

Although my dad’s Winchester is priceless to me and I would have paid any amount to get it back to what is was prior to it being broken, the cost of the work was less than what I would have paid for a brand new stock. The care and attention to detail Bart had taken working on my dad’s rifle allows for the legacy of my dad and his rifle to live on and for me to share a lifetime of memories with my son.


“What is really outstanding is the level of service provided; this shop is the only place I will entrust my guns to going forward. Bart and his staff are experts at their trade and true customer service experts as well. My hat is off to Bart and his shop!”

My spouse saw an e-flyer from Bart Miller Legacy Gunsmith that mentioned shotgun fitting. Neither of us knew exactly what a “shotgun fitting” was or what it entailed. After recent frustrations at some sporting clay’s outings my spouse urged me to call and set up an appointment. At an earlier point in my younger years I had been able to keep pace with my brothers and father, but this would no longer be the case. I had a horrible outing at a large charity event and was mortified and my performance. It is not easy to put into words how your shotgun fit changed my sporting clays’ adventures. The time you spent in the fitting appointment was excellent, clear, concise, simple and systematic. Your skills and direction provided the “click” in a profound light-bulb moment as the pieces for clay’s came together. The plan you laid out was perfect for me.

Over five outings, I followed your advice to the letter, and the transformation began to take hold. As a direct result of your fitting appointment, my scores more than doubled in the percentage of hits. More importantly, the fun and satisfaction of shooting clays was back!

Anyone wanting to improve their fun and skills in the sporting clays arena should schedule a fitting appointment with you. You deliver and then some with the suggestions, observations and the results.

Thank you Bart so much for your time and expertise.

Just a short note of thanks for helping me with my CZ during the Insight training last weekend.  Once again Legacy Gunsmith was there when we needed help.  And your suggestions about how to improve the firearm’s performance with a simple change in my stance worked perfectly.  Of course the fiber optic fix for my front sight was, from an ‘on the spot’ Pit Crew perspective, quite invaluable to Susan and me, and ensured our uninterrupted attendance at the class.
Please extend our thanks to your team as well.  On the rare occasions when you are not there, the quality of their work and their routine expert advice is always greatly appreciated.

I had some gunsmith work done here by Bart Miller. My issue was a nasty chip in my rifle stock that was somewhat large and in a very bad location that significantly reduced the value and eye appeal of my rifle. Bart was able to expertly repair the chip and did a masterful job of blending the new wood with the 50 year old finish. I was impressed by the craftsmanship and the price. It’s very hard to find skilled gunsmith labor for a reasonable price in the metro area but I found my new goto guy for all my future gunsmithing needs.

The term “elan” from the French language describes a property of elegant “vigorous spirit”, and the related English term “elance” describes a thrusting or hurling. Such terms well describe the recent 1911 build done by Bart and his staff at Legacy Gunsmithing, straight through the initial process of composition to the final product. Bart and his staff were straightforward in practical suggestions and with a vigorous hands-on build from scratch components, this sharpness of attention to detail resulted in the elegant behavior and fine function of the 1911 firearm.

Tactical components and a Damascus slide were solidified and tuned together over time with the final result represented as a functional tack driver with its own inherent spirit and balanced beauty. It is an exceptional end product from an exceptional staff.

What outstanding customer service the Centennial Gun Club provided me this week. I own an automatic that I carried when a police officer, but having changed careers haven’t fired in several decades. My wife used it for some firearms training and experienced consistent jamming. I brought it into your gunsmith shop – my first time visiting the facility. Steve provided a very welcoming/friendly greeting and asked how he could help. He listened very patiently. I was expecting to need to leave the weapon to be looked at over a period of time. Steve demonstrated a strong understanding of firearms and after looking it over asked if he could fire it to see what might be the problem. In a short time, he came back and advised the problem was not the firearm – but was the magazine. In a matter of minutes the problem was diagnosed and recommendations provided. WOW.

I was amazed and very grateful. As icing on the cake – Steve even thanked me for letting him shoot my sidearm!

What a great representative and knowledgeable staff you have. Two other gentlemen – whom I did not get their names – also weighed in and one did a modification of the magazine lips.

Thank you for having such a great team. I will certainly be sharing my experiences with your team to my friends.

I brought my LCP in last night intending to drop it off and wait for 3-4 weeks.  I was greeted by Jeff, who said “hold on while I go take a look at it”.  He took it to the back, and came back within 10 minutes with my LCP performing as it should.  All he asked for was “good will”.  Amazing.  Your team will certainly be at the top of my list of providers when I need any future gunsmithing services… and I’ll tell anybody else I come across, too.  Thanks to Jeff, you, and your entire team for being customer service oriented, and for being a great bunch of guys.

Dave J.

So far my experience with Centennial Gun Club has been superb!! Looking forward to shedding off some rust and improving skills. I want to keep advancing thru your courses.

Dean S.

It has been such a pleasure dealing with you!  When Warren Watson of Warren Watson School of Shotgunning recommended that I use you for my shotgun fitting ( because you are one of the best gun fitters he has used over the years) I didn’t doubt his word!  So I took my new Browning White Lightning to you at Centennial Gun Club.  You spent time with me, explaining exactly what you you would do to my gun.  You were also able to simulate how the new fit would feel, by using temporary materials on the stock so I could mount it.  You gave me a reasonable completion date as well.

I have had many compliments on your work since that first meeting.  I was so please, that I returned a month later with my Browning XT!  You had kept files on my first gun, so you were able to duplicate the stock work on my 12 gauge.

Many, many thanks for your expertise and service.  I am certain that Centennial Gun Club feels fortunate to have you there with them.


This review is strictly regarding the team at legacy gunsmith inside the gun club. I recently came into possession of about 7 different guns. I first took them to somewhere else to try to sell them and was treated like some idiot. I can only assume because I didn’t look like a typical gun guy they wouldn’t give me the time of day or any fair offers. (joke’s on you as I’m a military veteran with more gun experience than they seemed to have) what a refreshing change of pace coming into see the team here. They were all super friendly and let us drop off the guns and go about our day. When we came back, they gave us the market price on all our guns, even the ones they couldn’t buy. For the ones they could purchase, they made a fair price (70% of market value) and cut us a check! Even gave us an offer for a gun they they didn’t originally want but did it because we sold them the ones they did! Best of all, the customer service here represents a true American way. We love our country, our guns, and our family… They treat their customers like family. For that reason, we will only do business here moving forward.

I own a Glock 23 that I purchased and installed a laser light to.   I had tried to attempted to align the light myself with negative results. I contacted two people to assist me in this challenge and both advised me to just remove the laser because they are worthless.  My contact with these people made me feel like a super novice who knew nothing about firearms. FYI , I retired as a criminal investigator after more the. 20 years. Now to the reason I  am writing this. I contacted Mike Mitchell at Centennial Gun Club and told him my challenge.   Mike listened and advised me that it was probably an easy fix and I should bring it in so he could look at it.  He gave me an abbreviated idea of what might wrong that I could easily understand. When I brought my Glock in and Mike looked at it, he advised to come back in 15 minutes. When I returned he showed me how it now worked. Mike’s customer service skills are over and above what is normal in the business world and you should be commended for his hiring. Thank you and Mike for correcting my challenge with my weapon.

Your man Jacy got my M17 rear sight fixed in no time! I cannot say enough about what a warm and expert guy he is. So glad to have this level of expertise available to us as members of CGC!

This may seem like an unusual compliment but I’d like to thank Centennial Gun Club for helping me decide NOT to buy a particular handgun. I’ve never seen another gun store that will let you try a pistol or rifle before deciding whether to buy it. (Used firearms, not new, I understand.) There was a used pistol that looked like it might fit the bill for what I was looking for but after firing it I decided it wasn’t a great fit for me. Club staff actually encouraged me NOT to buy the gun when seeing that I wasn’t loving it. I really appreciate that level of looking out for your customer. It’s part of the reason I’ve encouraged many friends to buy their guns at Centennial Gun Club and why I purchase from you as well.


The Signature Used Gun Difference

A Legacy Gunsmiths signature on each certification form is our way of assuring you we have personally inspected this firearm and it has passed our certification process.

Here’s a behind the scenes look at Legacy Gunsmithings used gun purchasing and certification process

The Initial Inspection

We take the time to get familiar with each gun that comes in for sale or trade by first giving it a thorough visual inspection. We check for things like:

  • Cracked stocks
  • Bulged barrels
  • Surface rust
  • Has it been altered

Then we look at the make, model, caliber, accessories etc. We also try to gain some insight as to its history from the owner. We’ll explain the specifics of how our purchasing program is structured so the customer can be a part of the process as it moves along.

Establish Finish Originality

Perhaps no other factor contributes more to, or detracts from, a gun’s value than whether it’s been refinished or not. A gun can easily lose half its book value, or more, if it doesn’t have the original finish. In addition, the difference between a properly refinished gun and a poorly done one can also make a huge difference. It’s important to keep in mind that gun value blue books only give values for guns in their original condition.

Note: (Making a determination on originality is not always an easy task. This is where the experience of our gunsmith staff comes into play. For over 30 years we’ve had the privilege of handling a wide variety of guns in their original pristine condition.

The first hand experience we’ve gained from having personally performed restorations over the last 3 decades helps give us valuable insight verifying originality since we had the opportunity to see the gun before and after it was redone.)

Percentage of Condition

Condition, like beauty, is in the eye of the beholder and therefore open to interpretation. Fortunately, the gun Blue Books recognize this and have done a great job of providing the “tools” to help establish percentage of condition both by description and photos.

Establish Fair Market Value

We typically start the research by looking at industry standard firearm Blue Books. If we need to find more information, or additional comparable guns for sale, we’ll often go to the internet. Since the internet has countless listings being added and removed on a daily basis it can also be a great barometer for the gun markets ever fluctuating pricing.

Finding Common Ground

1) We review the information we’ve gathered with the customer to make sure they’re comfortable with everything.

2) Our goal is to reach common ground on the gun’s value. 

3) If everyone’s comfortable and confident with the information and the terms we then move forward. 

4) After the gun is purchased, it goes through our certification process.

The Certification Process

The top 2 priorities we keep in mind when we certify a gun is to make sure it is:

  1. Safe to shoot
  2. Reliable

We perform numerous checks on a gun to make sure it is within safe operating specifications.

We inspect each gun thoroughly, lock, stock and barrel.

The list of items we check can be quite involved and depends on the type of gun, of course. There are times when it makes sense to certify the gun before we buy it.

Sometimes we run into situations where, although the gun works, it’s out of spec. When this happens, we’ll take the time to bring it back to the proper spec’s. Think of it this way, just because your car runs, doesn’t mean it’s running correctly or at peak performance. In other words, things can “run” and still be out of spec!

If everything passes inspection we test fire the gun before it ever goes out for sale to the public. We provide a certification form with each used gun we sell with our gunsmith’s signature on it to show it has passed our certification process and it’s safe, reliable and ready to go. (There are of course a few exceptions like when there’s no ammo available or it’s an unfired gun).

Bart Miller

Bart Miller has made a living as a Gunsmith in the Denver area for over 30 years. He graduated the local Gunsmith School, the Colorado School of Trades, in 1984 and sits on their advisory board. He is also a certified Gunsmithing instructor. Bart started his gunsmith career in 1984 when he was 21 working for Gart Bros. He managed the repair shop for most of the 15 years he worked there. He and a business partner started a small retail gun store that was open for 5 years and specialized in gunsmithing which he managed. Bart sold his interest in the business and set up a gunsmith shop at a local gun store when an opportunity to work for Bass Pro Shops became available. He was employed by Bass Pro Shops for 10 years where he managed a 5 man gunsmith shop as well as their Fine Gun Room. While at Bass Pro he created an annual shooting event called the Generations Classic Sporting Clays Shoot where folks of all ages could get together to pass along our shooting heritage, introduce them to shotgun shooting sports and get the chance to experience what it’s like to shoot collector and high end classic shotguns from around the world. Bart has gained a strong following performing shotgun fittings for all ages. He works closely with several local professional shooting instructors. He has been a guest multiple times on local ESPN radio stations covering various aspects of gunsmithing and gun collecting. Bart has spoken at Brownells Gunsmith Career Fair several times presenting two seminars he created called, “Trouble Shooting Firearms” and “How to Provide a Great Customer Service Experience.” These seminars are now part of the curriculum at the Gunsmith school. Bart wrote an article called “If this old gun could talk” for an online magazine.   It gives a behind the scenes look at the firearm trade-in process and the importance a gunsmith shop can play. It also taps into the historical and sentimental aspects of gun ownership. Bart has performed countless appraisals for the companies he has worked for over 3 decades and his own mobile appraisal business. Bart has re-barreled guns for a local S.W.A.T. team and does design and custom work for people with special shooting needs. One of his hobbies is to do R&D work and build prototypes. He has been issued two patents. His primary gunsmithing focus is on the design and function of guns, what makes them run and the importance of customer service.
