OK, I've got a couple of glasses of wine in me so I'm feeling feisty. I own most of the major calibres for auto handguns - several niners, .45, .40, .357 Sig, .380, 9 mak, .32, .22, .38 special...
If it takes you more than two shots of 9mm to put someone down the problem ain't the gun or the round baby, its the friggin idiot carrying it. My usual carry piece is my Kimber Ultra CDP in .45, not for the round but for the way it feels and how it carries. I'm equally comfortable carrying my Kahr MK9. Why? Because I phucking hit where I aim.
The only reason a 9mm bullet is going to annoy someone is because I've just put the phucking thing between their eyes and they won't be getting that hummer they were rushing to the corner to get from that nickel ho with the money they hoped to mug from me.
OK, I've said my peace. BTW, remond me not to ever bring your father's partner to a gun fight, he sounds like more of a threat to me than the bad guys. Your dad however can watch my back any time.
