Hi, my USP hard as a rock after installing Match Trigger Kit. I perform the internal polishing of the pieces following this tutorial to later install the Match Trigger Kit purchased from an H&K dealer following the Toosixy tutorial.
After the assembly, everything is very hard ... the trigger, the hammer, the safety lever ... and I do not know if it is normal but the trigger has a very long trajectory.
I have disassembled and assembled three times and everything remains the same. What am I doing wrong?
