I've had several .45's in the past few years, they are as follows:
Glock M21 - Bore to wrist axis made this gun easy to shoot with. Intrinsic accuracy was very good, practical accuracy was great. Extermely feed and fire reliable. I've had two of these. Five Winchester 230 Black Talon shot sub inch at 25 feet off-hand consistently.
Sig P220 - Great gun. Intrinsic and pratical accuracy both great. More accurate with more loads than the Glock, but a bit harder to control for fast follow up shots. Five Remington 185 Semi-Wadcutters and Federal 230 Hydra Shocks sub inch 25 feet
Kimber Custom Classic - Great gun now. Had to have a smith tune it up. Now it's one of my all time favorites. Intrisic accuracy is decent, but not quite on par with the Sig. Probably equal to the Glock, but I have not found its' favorite load. The Kimber's pratical accuracy great, its easy to shoot well and fast. Five into 1.5 off-hand at 25 feet Winchester 230 FMJ, Speer 230 GD, Speer 185 GD +P, and Federal 230 Hydra Shocks.
H&K USP Tactical - Really new gun to me. So far its' intrinsic accuracy is the best I've had. Practical accuracy is great, even though the grips a little thick and the slide is a little tall. Five shots sub inch with Winchester 230 FMJ, Federal 230 Hydra Shocks.
The .45 ACP is my favorite pistol caliber. I haven't run accross a bad shooter in this loading yet. Good luck with your search.
