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:
The parts provided – control latch, extended sear roll pin and firing pin block spring – are designed to be installed together as a complete system.
The kit works with all variants of the HK USP and HK45 – both DA/SA and LEM variants – with or without a thumb safety.
Our kits will not fit the following variants:
These parts are intended for installation by a qualified armourer or gunsmith. In some cases professional fitting will be required by a trained, qualified armorer/gunsmith who is very familiar with the pistol’s action. This is due to the varying tolerances present in all mass-produced firearms. Although kits fit with no issues in a great majority of pistols, Grayguns is unable to guarantee perfect functionality in every instance. Grayguns does offer installation services for all parts kits we offer.
Our gunsmiths have determined a variance in some HK45/USP trigger bars. Some guns have an angle cut on the front side of the sear on the Trigger bar. We have found that installing our parts in a firearm with the extra cut will induce some issues within the gun. In Double action mode with the safety on the trigger bar allows the hammer to drop on to the catch as if it were being de-cocked. We do not recommend our parts being used with a Trigger bar that has this extra cut. However the gun will not go off in the case of the extra cut. Please consult with your local AUC/gunsmith if you do not know how to check your trigger bar.
