I have carried as small as .22 mag, and as large as .45acp. I prefer to carry at least .380, don't really have an upper limit. That said, I'm firmly in the camp of "any gun is better than no gun", so if all that's available is .22LR, I'll carry .22LR. It beats being unarmed.The conventional wisdom, for as long as I can recall, is to carry a handgun in the most potent cartridge that one can safely and effectively carry, draw, and shoot at an interloper. It makes sense, of course; if a situation has become so dire as to necessitate employing a handgun against another human being, well, it better be effective at stopping the altercation fast.
On that score:
Thanks for sharing.
- What is the absolute smallest, lowest power cartridge you would and have carried for personal defense?
- On the flipside, what is the largest, most powerful cartridge you would be willing to carry?
