I wonder why nobody ever thought to ask this before?
I carry with a round in the chamber. If I don't want the gun to fire, I don't pulll the trigger. If you can't do that, get some OC spray and a rape whistle.
Most police officers in America carry a Glock, every one of them carry it with a round in the chamber. Many of them d0on't even shoot as a hobby - the gun is just work equipment - yet they mostly manage not to shoot themselves. Those that do shoot themselves do it by pointing the gun at themselves and pulling the trigger.
This is the internet - you will never learn to shoot here.
