Grayguns HK45 Straight Trigger, Black

HK45 Straight Trigger

Designed by Keith Hosey, Grayguns’ director of gunsmithing, the HK45 Straight Trigger is a first in the market. The trigger reduces overtravel while featuring a 90-degree optimal trigger break.

This HK45 straight aftermarket trigger design allows for lower finger placement and may provide a 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. It is precision machined from tool steel and heat-treated adequately for optimal wear resistance. It is hand-inspected and finished to ensure a quality trigger we can stand behind for life.

Finish

Black Oxide – Our high-quality blued finish is our standard for this product.

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.

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 Grayguns.
