The double action pull or the single action pull is not near as good as my P2000. The P2000 is about perfect. Would the Grey Guns short reset help? My USPc 9MM is the D/A,S/A with a decoker. Is this the model 3? Man, this USP is accurate. It will out a round hole at 20yds? Can you buy the short reset kits now? I know they were out of stock.
The short reset will not have any effect on the pull weight, hammer and trigger return springs do. Also the the mechanics, leverage of the model you have.

I don’t know about the P2000 but the P2000sk has a longer reset than the USPC. I put the GG short reset in the P2000sk so it would be the same as the USPc.
