Problem in reassembly of S/42 Luger

[Bob G]

It really sounds as if the effort to re straw some of the parts has had quite a bit to do with the original problem. He states that after the re straw attempt, the pistol would go back to about 3/8ths of an inch before jamming up. He may have applied too much force to try to push the bbl.-receiver back into battery. After it became immovable he applied a hammer and punch(CRINGE) and now the major problem is it will not go anywhere near the original position. After the re straw effort, it sounds as if the receiver lug may have been hitting the take down lever?
