A customer's 1911 slide stop pin walked out during a test fire and I had to figure out why
I was at my bench in the shop last Thursday, test firing a customer's old Colt 1911 after a basic clean and check. On the third round, the slide locked back way too early. I cleared it and saw the slide stop pin had walked out almost a quarter inch. My heart just about stopped. I took it apart and the pin itself looked fine, but the little notch in the frame that the pin's leg sits in was worn almost smooth from years of use. I didn't have a new frame on hand, obviously, so I had to get creative. I used a small round needle file to carefully deepen that notch by just a few thousandths, making sure not to change the angle. Reassembled it, function checked it a bunch of times dry, and then test fired a full magazine without a single issue. The fix held. Has anyone else had to do a micro-adjustment like that on a worn 1911 frame, or is there a better way you'd go about it?
