Springfield XD 40 subcompact and S&W M&P shield, love my new Shield, the XD may start to get very lonely....chose m&p 9c on the poll, shield not a choice...
Depends on what you mean. The most carried civilian caliber is the 22lr. As far as the firearm that is a crap shoot at best as it depends on two things what you like and shoot well or what you have. I carry USP FS .45. I used to carry a 1911 years ago but when the USP came out and I got my fist one and realized not only how well it functioned but also the reliability and the accuracy I was hooked. My daughter shot my fs so much she to got one but later switched to a compact usp. Let us not forget this poll like other depends on those of us active in the forums and talking about it. The majority of those who carry never tell anyone they do so or chat about it.
M&P 40 Shield is my new fav in Texas heat with my S&W 340 SC in the front Pocket.
Oct thru March G20sf or 29sf in a Smartcarry with my 340 don't pocket.
