My box stock MKIII Browning Hi Power in 9MM is my most accurate centerfire handgun with factory loads or my own reloads. More accurate than my Springfield and Colt 1911's, and my HK USP Tactical .45 with match trigger. Is it close? Yes, I am talking about very small margins of accuracy, but I can get consistantly better groups with the Hi Power in 9MM, than my .45's. Not a statistically significant sample, and just my own anecdotal experience.
