I am the owner of an old Crosman 1300 air pistol, which I've had since I was 11 or 12. For the last couple of years I've had a replacement screw of slightly the wrong thread doing duty as the rear sight securing (windage adjusting) screw. It only ever bit by a couple of threads, but these are now gone and the screw no longer holds.
Has anyone out there got a spare I could scrounge/buy? Failing that, does anyone know for sure what thread and length the original screw was?
I've e-mailed Crosman with this question but had no reply. I'm not entirely sure, but I think this is a different screw to the one fitted to the later 1322 and 1377 pistols.
