311E misfire

[Woody101]

I have a 311E 20 gauge. The right barrel misfires (light hit) 80% of the time. Replaced hammer springs and firing pins. Pin hole looks large. Any help out there?

I just had mine apart today to install new reduced springs. I'm no gunsmith but could the firing pin not be hitting far enough.

When apart I noticed the screw right next to the firing pin. This sets the pin strike depth. Maybe you need to set it so the pin strikes deeper. Is there a different strike depth between left and right.

Hope it helps
