Brownells has a Firing pin protrusion gage - http://www.brownells.com/aspx/NS/store/P...ROTRUSION+GAUGE

You can probably make something similar out of a 1/4" threaded rod coupling and a smooth ended bolt, and measure the depth with your caliper. Hope that makes sense.

If you still have a wee bit of drag, and the pin is maximum length (.065"), try shortening it a wee bit more to say .060", or even to .055", if no misfires are happening. Big "IF".

As an alternative to heating and rebending the cocking lever, perhaps you could soft solder a piece of shim onto the right hammer's cocking face? Or perhaps a drop of steel tig welded to the face of the right side cocking lever?

I'd make a domed punch out of brass to start the pin out, then use a long pin punch with a piece of cut brass shim on the end to drive it out the rest of the way. A dab of grease will hold the brass shim on the end of the punch. You can perhaps find solid brass in 12" lengths at some hardware stores and hobby shops also to make a punch out of.

Best of luck with your pins. Joe
