I went to the range last week and ran two boxes of ammo the my 1911A1. So I figured it'd be really dirty and the palm safety was not working as new so I decided two kill two birds with one stone. It turned out I had broken the toe off of the spring last time I had it apart and it finally must have moved enough to cause problems. To the gunsmith who made it I went, whining all the way and he made me take it all completely apart, which I'd never done before and clean it properly. Then he gave me a new one, showed me how to put it in and told me to never let my gun get that dirty again! So much for, He works for me.
