As a person who prefers double action pistols, I went looking for a high capacity .45, and I finally decided on the USP. I narrowed my search down to 2 pistols, the Sig P220, and the HK USP 45. I ended up buying the HK USP 45 for the slightly lower weight, and the high capacity magazines. I could not ask for more in a double action high cap .45. This pistol is amazing, from the aggressive stippling on the grips and great ergonomics, to the crisp trigger break and steady recoil. I own several other hand guns, a Beretta 96fs, a Kimber Custom II 1911, a Smith and Wesson 67-1 .38 Special, and a PX4 Storm Sub Compact 9mm, and I have to say, this is slowly becoming my absolute favorite pistol to shoot. If you're a recreational shooter, or a service member who's looking for the characteristics of the .45 caliber in a high capacity polymer double action pistol, I'd be comfortable saying in my opinion, HK should be at the top of your list.
