Breechblock pin

mrerick · 04-18-2017, 09:50 AM

One way to check is to try a replacement pin in the forward toggle and breech block holes to see if there is any play. If there is play, then wear is contributing to the problem. I had multiple standard size pins snap in a luger that eventually required an oversized pin.

If it seems to fit properly, try shooting it. If there are still problems, the pin will snap apart again.

When Mauser re-engineered things in the 1970's, they reshaped the ends of the pins (concave rather than flat ends). I believe that this was to improve distribution of the forces acting on the pins during the firing cycle.
