One of the best .45s available
I've had a USP 45 (full size) for about 6 years and it is a wonderful gun. It is accurate and reliable, and still looks as good as when I bought it. The gun is built like a tank, and when you strip it for cleaning you are struck by how substantial and well made the parts are. If I had to take a chance on taking any new handgun out of the box into a gunfight with no testing, it would be the USP 45.
It is a little large for carry, but okay under winter clothes. If carry were my main objective I would get the compact version of the gun.
Mine has the stainless slide:
