The new pin and spring worked perfectly!! The old pin is about 3/16" longer than the new one, I think I may trim some off and try it again to see what happens

Now on a few rounds the slide will not go into battery, stops about 1/4" or so short and take some pushing to get it to go. Sometimes I remove the mag put the round back in and rack the slide, this works fine on the round that just jammed up. It does this with all magazines. I'm thinking something needs to be polished? Anyone have ideas??
