I just got back from putting 200 rounds through a new USP9 with a wide assortment of ammo such as Lawman 115 gr TMJ, Speer 124 gr +P GD's, 9BP, 9BPLE, and one mag of Ranger T +P+. The only ammo that seemed a bit hot for this pistol was the Ranger T +P+. All the others fed and grouped well and above all, I had no failures-a real joy for a change. I must say the S&W 4516-1 that I also took alone for the ride gave the same performance with 230 gr GDHP ammo and 200 gr LSWC's. These are two pistols you can bank your life on. I left the range a happy camper and not with my face on the floor board like I 'd have when I'd leave the range after a day of fighting with the Commander. I'm not sorry I traded it.
