I have a SW 1911. At 200 rounds the factory slide stop sheered off and I replaced it with another one. I don't remember what brand. Anyways. now at 1k rounds or so, the slide stop will not engage after the last round is fired with either of my 2 magazines. I can manually push the slide stop up and it goes in, however it feels like it is binding slightly or there is slight resisitance there. Do slide stops get bent over time? How can I diagnose what the issue is? Or should I just call SW and send it back to them?
