——aaaannnnddd putting a safety on is way too much trouble?
No safety on the civilian P320 as far as I know.
In a life and situation a safety can be what gets you kilt.
Carrying “cocked and locked” can be a dangerous circumstance depending on the design of the weapon. That’s why the 1911 has three safety features to prevent negligent discharge. If I was to chose to carry with a chambered round, it would be in a 1911 or a double action revolver.
