Hi Paul,
Just to let you know, the 586 shoots well. I put about 100 rounds using all of my usual loads and primers as well as a few commercial rounds and had no light strikes. Thanks again,

Blackhawk, CO

Hey Paul,
Just wanted to say thanks for your work on my m14. Took it out to the range on Sat. Runs like a proverbial top- no failures to feed, no jams with a whole bunch of different ammo. Really appreciate it.

Boulder, CO

Hey Paul,
Thought I'd let you know that I've put just over 700 rounds through the XD-40 since you did the work on it and not a single failure to battery or other feed issue. All magazines have been used and all types of ammo (including the original problem Remington ammo) as well as my hand loads and not one problem. Thanks for the great work!!

Evergreen, CO

Now that I've had a chance to do a little more pistol shooting, I wanted to express my thanks for the extra time you took with us - and interest you showed in us - regarding the Basic Pistol Class. Taking us shooting at the Clear Creek range - dry-firing at your shop - all went beyond what was required for the class - and was greatly appreciated. As I've had the chance to shoot more, some of the things you taught us are making real sense to me. The little Taurus has functioned flawlessly ever since you fixed it for me.

Jefferson County, CO

After our IPSC match today I took the time to shoot 3 10 shot groups over my Chrony. I used a rest and shot at 50'. One group is about 2" and the other 2 had a few fliers. I believe that with more concentration and effort I could do even better. It certainly shoots better than I can hold it. My average velocity is 850 fps with 230 gr. bullets and the power factor is 195. I am going to lower the charge some to reduce the recoil improve my control more. This piece is so much better than the government model that I was using. I really appreciate the checkering on the front and rear of the grip. It helps me to keep a good grip when shooting. My score has improved remarkably with this piece. Of course there was a lot of room for improvement too...and still is. See you soon.

Evergreen, CO

Got to put 350 rounds through the Thompson .45 this past weekend without incident. Fired Remington, Winchester white box, tula ammo, sellier and bellot and mag tech. The only ones with punctured primers were the tula. STAY AWAY FROM THOSE!, as they were also rather inaccurate. All other primers were still rounded outside of primer mark and intact. The firearm is so much better now and was finally a pleasure to fire. Thanks again for everything. Your service was immediate, spectacular and top notch. We'll be talking soon about concealed carry, lessons, a new barrel and range time.
Thanks again for everything. It is much appreciated.

Rollinsville, CO

Paul did a super job on my 1911 that was very rough. This was bought from a 3rd party, Paul explained the issue, took his time and turned a beat up pistol into a work of art. I highly recommend and will use his services going forward."

Jim in Dallas, Texas

Hi Paul,
Just a note to thank you for the great job you did on rebarreling my S&W 1917, .45 ACP revolver. Your work was superb and the 97 year old warhorse shoots perfectly. My friends in my gun club are uniformly impressed.
If I encounter anyone who needs a competent gunsmith I'll be happy to pass on your name.

I like Paul / The Mountain Gunsmith, for service the most. If you want a gunsmith, repair services, to buy a firearm, take firearms training or many other services related, Paul is your best bet for customer service. I was looking for a muzzle brake and other services for some new guns I purchased for hunting and tried several gunsmiths, whom did not even bother to return calls. Paul is different; He will return your call, is ready for your business, and ready to help, also making valuable suggestions that you may not have noted about your guns. It has been several years before handling firearms for me, and Paul also gave me invaluable safety advice, as my background was mostly in archery hunting, with my to transition to rifle hunting, as well recreational shooting. Take time to listen to the Sage of Firearms, Paul Arocha, The Mountain Gunsmith. It's simple for me, Paul's there for my firearm needs. I have told several friends as well, "Paul's the Man. "
