That looks like a good solution to a forever problem.    When are you willing to make them available for us?    Sooner or later the pins will be all broken and no longer available and our prized M50s will just be a boat anchor,  mine break about 1000 rounds.

I'm ready to try one ,   please

Not my video, the guy who made it used to post here, but hasn't provided an update on his quest for a firing pin solution.

This is his thread from here

Broken firing pins are probably the most commonly encountered issue with Reisings. PaulF on this board posted an excellent "How To" regarding a solution to this problem. The post may be found at the following link:

I did that mod and my pins still broke.   I load my rounds for the gun and I'm using a much lighter powder load and hopefully that helps.   I'm going to decrease the load till it will not function and then go back up.   Still in the process with this endeavor.

Merely doing the inertial firing pin conversion may help but it  does not fix the problem.  Shortening the groove in which the retaining pin rides is critical because it limits over-extension of the firing pin.  The other critical mod is chamfering the square shoulder behind the firing pin tip.  The square shoulder on the Keystone pins sets up a stress concentration in a highly stressed area.
