As I've posted before, I recently picked up a Springfield Armory "Loaded" stainless in .45 caliber. I'm curious... what kind of accuracy should I expect from this gun? At 50 feet, I've been getting groups of just under 4 inches, which is somewhat disappointing. With my Sig Sauer P266 at the same range, I often get groups of under 2 inches. Am I just hard to impress?
