Nope. I kill paper. I've used the occasional BB to dispatch or disuade birds from roosting next to my bedroom, but that was 20 years ago.
I do NOT conceal carry, though I've dabbled w/ the idea.
I did not need my weapon in military service, fortunately.
While I subscripe to the artfully described "condom principle," I'm not allowed to carry a firearm onto a base, which pretty much means there's no point in carrying one 75% of the time.
