It is fully compatible with the Grayguns Short Reset System for the HK USP.
Please ensure you review the Fit Guide and order the correct trigger.
We have a straight trigger in black oxide or nickel for the HK USP Compact pistol variations.
Description
Designed by Keith Hosey, Grayguns’ director of gunsmithing, the HK USP Full Size Straight Trigger for full-size variations is a first-of-its-kind in the market.
This USP’s straight aftermarket trigger design allows 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.

Nickel PTFE
Electroless Nickel PTFE (Teflon®) is an advanced, self-lubricating composite coating with PTFE particles co-deposited in the electroless nickel layer. Provides a hard, uniform, self-lubricating coating for our premium aftermarket triggers.
Physical Vapor Deposition (PVD)
This state-of-the-art process creates a molecular bond to the trigger, resulting in a durable finish. The PVD finish should not rust, discolor or tarnish. Availability varies, but options may include Blue, Flat Dark Earth and Oil Rubbed Bronze finishes.
Titanium Nitride (TiN)
A well-proven standard layer type through its balanced properties. The golden titanium nitride layer, abbreviated TiN, indicates the following properties:
- High hardness and adhesion
- Good chemical resistance
- Good temperature resistance in air
- Relatively low thermal conductivity
- Attractive, golden color
Titanium Carbo-Nitride (TiCN) (Copper)
The TiCN Copper finish features high hardness, low residual stress, good abrasive wear resistance, and high reliability in dry operations.
HK Straight Trigger Design & Photos
The Grayguns HK Straight Triggers for the HK45, P30, P2000, and HK USP are different, but somewhat indistinguishable at first glance. For this reason, the photos shown represent the finish and color only. The current production of the triggers includes laser markings indicating which pistol model the trigger fits. Early versions include a batch number. If you’re unsure of the trigger you have in your hand, please contact us.

Really nice quality part. Upgraded the trigger and also added the short reset kit. I was skeptical if I could Install the trigger but managed to get the job done once I found the right combination of tools (4) to the finagle the trigger spring.
Excellent trigger, fit and finish are outstanding. Shipping was prompt and well communicated. I paired it with the GG short reset system and absolutely love the feel of this combination. The HK match trigger is already an excellent setup, but this trigger’s action seems more consistent and repeatable at the wall and also the reset. I highly recommend this trigger., in fact, I have this trigger not only in my EDC USP9, but also in my USP45 Expert and the compact version for my USP9 compact. I personally wouldn’t think of running a USP without one. Well done Bruce and your team at Grayguns!
Great color in TiCN copper, almost perfectly matches my slide. The straight trigger is a massive improvement for what it is, a nice flat and wide surface for your finger to pull against. Definitely going on all my USP’s!
Got the Nickel PTFE trigger to go with my black and silver two-tone theme on my USP9. Looks so good and sleek, feels great compared to the stock polymer trigger, and the shipping speed was good. Love the trigger so much that I’m gonna have to upgrade the trigger on my USP45 as well. Just don’t know what color to choose.
I was in visiting my local gun store and I asked the owner if there were any aftermarket triggers for H&K pistols. He immediately went over to his computer and pulled up GrayGuns website and said to take a look at what was available there. I ordered the flat trigger for my USP 45 on GG website which was really easy, shipping was quick and the trigger’s quality, fit, and finish was exceptional. After installing the trigger I took the pistol to the range and it worked flawlessly and the feel over the stock trigger was a game changer. I have since ordered a trigger for my P2000sk along with some lighter TRS.
Thanks GrayGuns!
