I have that topped, at about age 7 I reassembled a 38 revolver and when the hammer jammed on the barrel I finally tried to slowly squeeze the trigger to release the hammer at which point the sound left me deaf, car was filled with smoke (seemed like slow motion) took a while before I was sure I hadn’t shot my leg but put a hell of a hole in the car radio.
Those were the old days.
I did essentially the same thing (except with my father’s rifle from the reserves) and in the kitchen.
Had to find the keys AND the combination to get to it.
