Grayguns HK USP, HK45 Short Reset System
Our Short Reset System for the HK USP and HK45 replicates the short reset conversion available in our in-house custom action work. Cut from bar stock steel, these kits provide an exacting fit for easy install.
The kit shortens the reset travel distance by about one-third, reduces trigger over-travel and reduces pull weight while maintaining all factory safety functions.

The parts provided – control catch, pin and spring – are designed to be installed together as a complete system.
