Problem in reassembly of S/42 Luger

[Lugerdoc]

Hoyt, I think that Vern may be on the right track. As you slide the barrelled reciever into the frame, check to see if the receiver lug (under the chamber araa) is hitting the front of the frame as it goes in. Perhaps, rather than grinding on your parts, a bit of lapping with some valve grinding compound, would be less destructive. TH
