My .380 and 9mm concealed carry pistols aren't legal hunting calibers and my .357 carry revolver doesn't have a long enough barrel. Still I wouldn't use them if they were legal. They are far too weak to guarantee a clean fast kill. I can shoot a .357 bullet, 22 grains heavier and several hundred FPS faster with a 6 inch barrel revolver and it's not my first choice of stopping big game in it's tracks. Also it's not something I conceal carry without a winter coat. It weighs almost 3 pounds.
