I recently picked up a 1989-vinatge Bulgarian-made Makarov. After cleaning away enough cosmoline to rust-proof a six-bottom plow, I found that it's really in quite nice condition and shoots like a dream. One minor problem I've noticed, though, is that the forward part of trigger guard does not want to fully seat up into the frame. It hangs about 1/16" inch low. You can push it up to where it's flush but it won't stay there. Does that sound like the trigger guard spring and plunger need to be replaced?
