I have a 1911 that was built by a gunsmith. At half cock, if you pull the trigger it will go off. I tried it a few times with a primed case with no powder, no bullet. Primer set off. Now I discover that it will also go off if your hand is not on the grip safty!
Just hold it by the grips and not engage the grip safty, pull the trigger and Boom. I think I will have it re-worked.
