Shooting a 1936 S/42 - replace original parts first?

[Lugerdoc]

Frank, I agree with Thor. It is highly unlikely that a 1917 LPO8 has survived this long without being shot. Also, I'd be surprised if the frame with stock lug, is original to your 1913 DDR rework, as the switch to stock lug frames ocurred in Dec 1913, so they are quite scarce. TH
