I have the full size .40, but fired the gun range's compact USP. Fun to shoot with low recoil (awesome HK springs!). I was shooting accurate and controlable double taps starting with DA. Trigger is very crisp and the reset is excellent. The gun may seem a little bulky for some, but it is a tough polymer nail driver. USP is my favorite gun (my p226 is next) of all time, and I have owned many handguns in 380, 9, 40, 45, 357. The USP has a safety, decocker and DA/SA, which is why I bought it over the P2000. Either gun is awesome, but I like the more options of the USP.
Which variant of P2000?
V0: CDA (Combat Defense Action) trigger system (SA/DA). Single-action trigger pull of 20 N (4.5 lbf) (+4/-2 N), double-action trigger pull 51 N (11.5 lbf) (±5 N).
V1: CDA trigger system (LEM). The LEM trigger is a dual-stage trigger that fires from a hammer down position in both SA and DA modes, but has an internal mechanism that is cocked with each cycle of the action. It provides a constant trigger pull of 20 N (4.5 lbf) (+4/-2 N).
V2: CDA trigger system (LEM). Like P2000 V1 but with an increased trigger weight. The trigger pull is 32.5 N (7.3 lbf) (±2.5 N).
V3: SA/DA trigger with a decocking lever mounted at the posterior of the slide to the left of the spurred hammer. Single-action trigger pull of 20 N (4.5 lbf) (+4/-2 N), double-action trigger pull 51 N (11.5 lbf) (±5 N).
V4: CDA trigger system (LEM). Like P2000 V1 and V2 but with a mid-range trigger pull of 27.5 N (6.2 lbf) (±2.5 N).
V5: Double-action only (DAO) trigger system. Trigger pull of 36 N (8.1 lbf) (±3 N).
I see the P2000 in the holsters of the Polizei all the time, but some have the USP. The bundeswehr (Germany army) adopted the USP. HK made the USP in an attempt to make a universal pistol for police and military.
