I presume you are thinking the full size version, not the compact. H&K makes superb weapons, but a few thoughts based on my experience with them. H&Ks are ultra reliable, accurate and can replicate the 1911 cocked and locked mode. They can also be carried in the DA/SA mode, the decocker can be used to "de-fang the snake" during weapon retention. They are not small guns however, and the compact verison is a mite chubby, and recoil control for fast shooting takes practice. The bore to grip axis is a bit high compared to a 1911, but it is a fine weapon. The ability to mount H&K's weapon light is a huge plus. I fired hundreds of rounds through USPs during classes at H&K training, (as did many other folks) and I never saw one them burp. Where .45s are concerned, 1911s will always be my favorites, but one cannot go wrong with an H&K.
