Ever seen a movie where some guy has to be cool and break into a room/building/closet with a padlock on it, so he goes and shoots it with his handgun, lock goes flying off, and in he goes? Of course you have. Well some old guy who kicks ass decided to hang up 5 tough padlocks in a field and tried shooting them off with a whole arsenal of weapons. Handguns (yes, even a .44) had no effect and rifles smashed through the locks, but they still held. So what finally did the trick? A shotgun. As Doom has shown us over the years in video games, if you need to get the job done, use a shotgun.
