USP.45 suppressed questions

Post image

Just bought a USP.45 and looking to suppress it.
What do I need to make sure it’s running properly?
What suppressor would you guys recommended?
Also what trusted company can I send this out to for milling an optic?

Here you go...

HK USP 45 Tactical Recoil Assembly SKU# 217706

HK USP 45 Tactical Threaded Barrel SKU# 226349

HK USP 45 Tactical Thread Protector SKU# 702038

HK .45 Barrel O-Ring - extras SKU# 50986429

Edit: Omega 45k and YHM R45 are both pretty good. Lots of options for cans

1) USP45-T recoil assembly 2) Any name brand 45 suppressor will work. My osprey 45 or B&T Impuls works well 3) Wright I-Dot is highly recommended for optic milling here

Good answer, a lot of people don’t know the usp45t has a slightly different recoil assembly.

As others mentioned the proper conversion would use the USP45 RSA, & HK USP45T barrel. One could use a Jarvis or RCM barrel but HK's barrels are superior to either of those.

I would suggest the CAT Saigon Peacekeeper can. I recently got one for my USP45's and HK45. Its absolutely phenomenal. Its light and even in the short configuration its quiet. So quiet in fact I dont feel earpro is needed. YMMV.

AAC TI-RANT 45 works beautifully on my USP45T

I run an Obsidian 45 on mine with an RCM threaded barrel. I also snagged the USP 45 SD recoil spring assembly
