Designed by Keith Hosey, Grayguns’ director of gunsmithing, the HK USP Straight Trigger is a first-of-its-kind in the market. The trigger reduces over-travel while featuring a 90-degree optimal trigger break.

This USP Straight aftermarket straight trigger design does allow for lower finger placement and may provide the feel of reduced pull weight. However, the trigger design does not reduce pull weight.

Made in the United States to high-quality standards, it guarantees the fit and finish Grayguns is known for. Precision machined from tool steel and heat-treated adequately for optimal wear resistance. Hand inspected and finished to ensure a quality trigger we can stand behind for life.

Many parts sold by Grayguns - including but not limited to triggers, trigger kits, internal components and spring kits - are intended for installation by a qualified armorer or gunsmith who is familiar with the firearm.

Although kits fit with no issues in a great majority of pistols, Grayguns cannot guarantee perfect functionality in every instance.

Due to varying tolerances present in all mass-produced firearms, professional fitting by a qualified armorer who is familiar with the pistol's action may be required.

Grayguns offers installation services for all parts kits we offer. If you have any issues or questions about the installation process, STOP IMMEDIATELY and contact the Grayguns Customer Service Team.
