hk usp v1 to v2 trouble shoot

[clipofblanks]

hi, i am having trouble changing variants on a hk uspc. i have purchased a v2 lever and completed the install. the problem is the pistol is hard to actuate the lever. safe-fire is very difficult and decock is very hard. has anyone have had this issue? just cant comprehend why changing lever from left to right will make actuation hard. i have double checked that all parts are installed correctly. i have even took it back apart and installed the v1 lever and it works perfectly fine. thank you

Is it still working correctly? Safe still prevents trigger from being pulled. Decock lowers the hammer to half-cock?

Typically, the right side lever should feel stiffer/more flexy than the right side lever. The detent plate profile is what determines how easy it is to switch between the different modes. The left side lever is right next to it, so it will feel more direct. The right side lever has to transmit the torque through the entire shaft. So it usually feels stiffer, even if you are using the ambi lever.

You can modify the detent plate to be less stiff by altering the profile of the ramp to each position. You can make it harder or easier too.

Yes it does function properly, safe, fire decock. between safe and fire is something i can live with, but decock is next to impossible and feels like something is going to break. ill look into detent plate modification. thank you for the reply

Try lubing the detent plate where the pin is.
