I have an SXP and have been trying to find a AR style butt-stock. I have found several for the SXP but they are considerably more expensive than those I have found 1200-1300. So my question is, Are the connections fron the butt of the gun to the stock really that much different? And if not wouldn't you be able to to use a stock designed for the 1300 on the SXP? .... I got the version that had 2 barrels one for defense and one for Game hunting, so my version doesn't have the pistol grip AR style butt-stock.
