With use, this is best de-cocker on any gun I tried. Design and location are perfect. No problems with accidental de-cocking while shooting, easy accesible for bouth left handed and right handed.I have a USPc 40 and was thinking of getting a P2000v3, but the decocker design & location is insane and crazy.
But if you prefer traditional style safety and de-cocker stay with USPc. But you may consider traditional style safety with all good sides of P2000 de-cocker: P30S/P30LS in V3.
