A properly maintained weapon will not go off until the humnan factor is introduced. About 15 years ago just to prove a point I set up a 1911a1 in a pistol vise aimed at ballistic jell target round in the chamber hammer cocked. It set there for 6 monthes and never went off by itself.
'It has been said that politics is the
second oldest profession. I have learned
that it bears a striking resemblance
to the first.' - Ronald Reagan
