Took my new to me USP 40 S&W out for the first time yesterday. It was also my first time with the 40S&W caliber. All I can say is AWESOME SAUCE, I shoot at 6" diameter steel plates from 7-25 yards off hand. My dad shot his gen 1 glock 17 with me and the HK won big time! Also the HK had softer smoother recoil than the glock which amazed me since it was only a 9mm and mine was a 40. I ran WWB,Federal,and Perfecta thru it with no issues for 200 rounds. Even all the sigs I have owned malfunctioned on the first trip. This gun is amazing, I spent all this morning cleaning it in detail and man oh man it looked like this thing was buried in sand!. All the enternal parts had so much gunk caked on them it looked like I just crawled from under the hood of a car when I was finished. But I am now 100% HK there are no others when it comes to a combat/pertection!
