I carry 24/7 I am a Federal Agent I carry a Sig P229 and a Browning Hi Power backup. Off duty I carry my H&K USP and a Ruger SP101 back up. While enfemme I carry a purse with a hidden pocket for my off duty backup my SP101. A few others brought valid points, they carry a knife, can't shoot someone, body is a weapon, those are all great and wonderful and if they work great, I have only one comment well three 1 never bring a knife to a gun fight 2 you cannot out run or dodge bullet and finally 3 find a freind that can shoot someone, kinda raw and I'm sorry for that but in line of work I see the horribile nasty reality of it all, and often ask had they been armed who would be notifing BTW is the absolute worst thing one person can do to another. Sorry for the gore but it's the truth........
