I need info on firing pins for my semi-auto Thompson. The last time I took it to the range the firing pin broke. Kahr has then as well as Numrich, I just don't know which one will work with my gun. I have a West Hurley 1927 a-1. The pics on the Kahr site look like mine but the tip looks longer. The Numrich site does not show pics but lists several. This looks like the place to ask. Thanks for the help
