Grayguns H&K HK45/USP Short Reset System
ESTIMATED DELIVERY 4-6 WEEKS
This product from Grayguns replicates the the short reset conversion for HK pistols found in our custom action work in a convenient, easy to install kit. These parts are precisely wire cut EDM from ground bar stock to exacting tolerances for easy install and a precise fit. They are properly heat treated and coated in a durable nickel PTFE finish for a lifetime of durability and smooth function.
The kit is engineered to provide several benefits:
- Shortens trigger reset travel distance by approximately 30 percent
- Converts the action to drive the sear directly off the control latch – instead of transferring energy through the catch – for a direct drive connection between the control latch and sear
- Reduced trigger over travel values
- Maintains all factory safety functions
- Simplifies install and reassembly as control latch can be installed separate from the catch. (Similar to the P30 and P2000.)
- Works with both DA/SA and LEM variants
- Included Grayguns Firing Pin Block Spring reduces stacking in DA pull and lightens trigger pull
Includes
The parts provided – control latch, extended sear roll pin and firing pin block spring – are designed to be installed together as a complete system.
- Custom-designed Grayguns Control Latch
- Custom replacement Firing Pin Block Spring
