Where's that dead horse beating gif when you need it? Somebody's probably already used it, though, as I haven't read much of this thread before posting. I carry everything from .22 to .380 to .45ACP to .357 magnum depending on mood, threat level, what I can get away concealing, season, etc. 9x19 is my favorite. I can almost always conceal my P11 Kel Tec. I like .45ACP, particularly my Ruger P90 that shoots it. Of all the calibers I carry, .357 magnum is my favorite. I've kill more with it than I have anything else and it kills well. I've killed with the 9 and the .45 in my hog trap and they don't measure up to the lightening death of the .357 magnum. I've seen it with my own eyes. Oh, they die, but they'll thrash around more before they go down. To me, .357 magnum (not sig) is where hunting calibers start. If you want an auto as good, you have a small selection of full size models to choose from in 10mm. But, ya know, for self defense in an auto, the .45 serves me fine. I'm not out looking for 10mms. I wouldn't hunt with the gun and I'm just as happy with a .357 magnum revolver, 3" barrel, which is easier to carry. Hell of a recoil and muzzle blast, not for babies, but it will end the fight post haste if you can shoot it. Some can't, so that's where the problem lies in such powerful cartridges in handguns. Everyone makes their own choices based on their own skill levels. I'm not stuck on one caliber, though. I believe more in shot placement and HAVING a gun when you need it. In the south, I just can't always carry a belt gun. And, frankly, I like my P90 over my P85 because it's more accurate and has a better trigger, not because of the caliber.
