I have a 1980 1377 with the sliding breech cover. The gun is in very good condition despite it's age and the use it has seen. My question is, the chamber cover is very loose and just falls open. Is there a way to tighten it up? I don't see any adjustment on the breech.
If its just falling open I am wondering if the bolt o ring might be worn or shrunken.
