Just finished cleaning my USPf9 after running 400 rounds through it at the range. When it goes to the range it typically gets 200-400 rounds run down the pipe each and every time without so much as a hiccup. It eats everything that's fed trough it and is the easiest gun to clean that I've owned. That goes for my other two USPs as well. HK may produce updated 'improved' pistols from time to time, but the USP will be a standard for years to come due to its reliability and simplicity. The P30 would have to be drastically better for me to move to it over my USP9 and I don't think it will prove to be. Neither will the HK45. When something works and works well I tend to stick with it. That'll be the problem with the new models coming out. Convincing current USP owners that they are so much better they should make the switch. Government agencies and law enforcement will be the primary buyers as they replace worn out equipment, or have the urge to update. I'm not sure private owners will be so eager to give up their trusty USP. I am a USP believer.
