i cant decide on which caliber to go with 9mm, .40s&w, or .357sig and i need your opinins. this gun is only going to be a carry gun, not a range gun so i am not worried about recoil. i actually had some questions about the barrel being fully supported and i know the .357 sig barrels are supported the best. anyways what do you guys recommend for a carry caliber, basically i mean the most potent. thanks for all the replies in advance.
