The H&K USP .40 cal variant 7 is the dept. gun for the NJDOC. Great gun. Very accurate. But it's a big gun and it's heavy with a couple of sharp edges. Has the magazine safety in the full size USP only and the #7 variation is DAO. The factory mags are metal and will rust if you don't clean them, but of course our dept. ranges run like the Post Office...rain or shine, in a foot of snow or 100 degrees.
You could buy a Glock 17 and be halfway to buying another one for the price you'll pay for a H&K.
Can't tell you how easy they are to break down. We're not allowed to touch them even in our towers at the prison. Come on duty, count your rounds, load up and holster. Unload it and pass a safe weapon to your relief. Period!
