Has anyone done anything to improve their firearm? Major or minor, tell us here...

I've shaved the trigger hump in an old mauser rifle (removed the second stage hump to give a smoother pull) and cut the barrel back about an 1/8" and re-crowned it.

Anyone customized a 1911 with aftermarket parts? I'm interested in getting another RIA 1911 and doing some work to it. I heard a guy say one time that he sold one and the guy put a little work in it and started using it at competitions. He tried to buy it back afterward without luck... :biggrin:
