Liner compensator - CMMG ZEROED .45 ACP Linear Compensator

I got this for a 1911 build as I wanted something before I got a suppressor. it did come with a crush washer, but I couldn't use it with the barrel. I managed to use blue Loctite and torque it down on the threads. It works really well and it is noticeably different. I didn't even need to change the recoil spring weight! Would I buy again? Yeah I probably would. (Probably better on a PCC)
