I have a little more sense than to say it to the wrong people, and yes sometimes you can't tell. But some people need to be told they are idiots, because they are just too dumb to figure it out themselves.
I always find a big bore, like my kimber or glock 45cal, does a lot more damage and is more accurate than some wanna be ganster. and with my conceal carry permit, I take it with me where ever I go.

A 16" mossberg 500 12ga might be a little harder to explain to the cops but it will definately get the job done. Just remember when
seconds count, cops are only
minutes away.
