If you ever purchased RMR .355 bullets, you may know their ogives can be pretty far towards the nose of the bullet. Well I bought thousands of them when they went on a huge sale for a bit there. Couple that with all my 9mm pistols that have tight throats, and I was having to load them short to the point that even I was a little sketched out. A few research hours later, and every reloading forum I frequent suggested these guys. Sent my barrels in with dummy rounds to achieve a perfect fit. Within three hours of USPS emailing me that they delivered my barrels, FEDEX emails me to say they're on the way back. If that's not fast service, I dunno what is. The barrels arrived, I cleaned them out, plunked my test rounds and a few others, and I was off to the races! Took them straight to the range where they ran every single thing I fed them, no matter how long I loaded the rounds. And they were just as accurate as before. They held on to that promise. Or maybe I'm a terrible shot. Who knows? Thanks Patriot Defense. You're my go to guys from now on!

turn around was very fast with excellent work on barrel

Great..plunk tests everything now and shoots great. No loss of accuracy. Now handles 9mm 148 gr hardcast.

Could not get my Rival SF to run in any configuration. Canik sent me a new extractor and spring, no go, then sent me a new barrel...still no go. I figured Id get Patriot to ream my original barrel.....installed it and the S runs perfect now with any ammo.....well worth it.

Super quick turn-around and works as advertised!

Very fast turn-around. Canik Rival factory barrel will now chamber and function with my OAL 1.35" 147 grain handloads, while retaining the factory barrel's excellent accuracy. Thanks for your great work.

I haven't put a ton of rounds through my newly reamed barrel but as of right now it's accepting loaded ammo much longer than it was before.

I have been having problem using a JHP bullets before it was reamed, now it’s working flawlessly. Service was fast and delivered back to me less than a week.

PD returned my email inquiry asking if they could handle CZ Shadow 2 barrels. That's the barrel no one wants to touch - even those who say they can do 'hardened' barrels. They said no problem . I sent mine in and with about a week turnaround time, I can now load out to reasonable length 1.135 - 1.1500 depending on the profile. No detriment to accuracy either.
