You are not alone. My AD was at the gun range and I left a hole in the ceiling. First time shooting an SKS that had not been cleaned. Pulled the trigger downrange and felt resistance until the point it should have fired and then the trigger just dangled. Had a full magazine, so I just ejected the round which reset the trigger and tried again. Same thing. Giving up, I set the butt on the bench to remove the magazine but first had to open the breech. When I touched the bolt, the gun fired. Range master accused me of pulling the trigger and kicked me off the range. Taking the gun apart, I discovered old sticky cosmoline all over the flat seer, keeping it from releasing properly. Things learned: 1. Clean any gun that has been in storage- especially surplus firearms. 2. Only load one cartridge in an unproven semi-automatic for the first shot. 3. Keep a weapon pointed downrange if ANY unfired rounds are still loaded during a malfunction. (Should of cycled until empty before pointing the gun vertical). 4. Never trust a gun to do what it is supposed to do until it proves that it will- every time.
