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.

This kit is specific to the HK USP and HK45 models with or without a thumb safety, including DA/SA and LEM variations.

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

Kits will not fit the following variants:

• Double Action Only pistols
• MK23
• Early USP models with joined one piece catch, control latch or models that have the short catch that stops the hammer rather than spur. These older versions are rare and usually easily identified because they lack the rubber coating on the hammer thumb stud.
