I had no idea this site existed. I duckduckgo'd primer size for 10mm and this site popped up so here I am.
G29, Tangfolio steel, and Witness polymer (that won't feed).
Primarily I'm here to try to diagnose the Witness polymer. I'm hoping some of you have solved the feed issue as I very much like the pistol feel and weight. I think it would make a good ccw.
Glad my search engine found the site.
