Went to the range, and even though the firing pin was .010" shorter, and is as short or shorter than any of my other Lugers, it still pierced the primer on the barrel I'm trying to save?.. I put the same ammo thru a known excellent working Luger and it DID NOT pierce the primers?... Soooo, the brass case mouth it going in past the chamber front edge, and then setting back over the pin upon firing?... Das barrel is kaput, me thinks?....

.... more as I learn it!.... Best to all, and thanks Doc for your replies! Always good to hear from you.... til....lat'r.....GT.....
