Ive decided that a XD SC will be my enxt carry piece. Coming from a p226 carrying this thing will be a breeze. However im pretty unhappy with the caliber choices offered by SA on the SC model. Ill probably end up getting a 9 because i spend allot of time at the range. However id prefer either 357SIG or 45GAP for a carry piece over .40 and 9mm. Are there any rumors around about theese being offered in the SC gun from the factory w/o conversion brl?
