I voted no difference, because I shoot groups like that from both my S&W, and Colt. Those darn guns can't hit the broad side of the barn. My son, often tells me, that he would rather stand in front of the target than beside me, says he'd be safer. Lousy guns.I hardly ever miss w/scattergun be it import or homegrown.
In DA my groups appear to have come down the same barrel at the same time.
