Most of you will know this, but a reminder wake up.
Shooter Lugers. Too long a firing pin will piece the primer and if it doesn't have post 1933 gas by pass cuts, on firing the high pressure blows the firing back as it has a seal. This compresses the firing spring, blows the firing pin retainer out the back of the breach block. Very Sad.
A friend did this and when mine wouldn't fire after the 2nd shot, I picked up the brass and knew what the problem was.
OK, remove blue, a spot of weld, then dress it up with the Dremel,
All my shooter have these 3 gas by passes cuts in them. Not hard to do.
Prior to this happen, I expected that there would be so much pressure, it would blow the sear bar out and do some really bad damage.
