I bought a M92 pistol and put the brace and a 4 piece brake on it. The hammer followed and basically it was a single shot. I sent it back to Century. They adjusted the fire control group and sent it back. When I got it back I tried it with the brace. It was still a single-shooter. The trigger would not reset. So I tried it without the brace. It worked fine. They are going to have another go at it with the brace on to see if they can fix it. I'd much rather hear from someone here on what having the brace the gun could do to affect the function of the fire control group so I could get it to work without sending it back again. Any ideas anyone?
