Grayguns, Inc. - Manufacturers - Top Gun Supply

Our Short Reset System for the HK USP and HK45 replicates the short reset conversion available in our in-house custom action work. Cut from bar stock steel, these kits provide an exacting fit for easy install.

The kit shortens the reset travel distance by about one-third, reduces trigger over-travel and reduces pull weight while maintaining all factory safety functions.

This kit is specific to the HK USP and HK45 models with or without a thumb safety, including DA/SA and LEM variations.

The parts provided – control catch, pin and spring – are designed to be installed together as a complete system.

Kits will not fit the following variants:

• Double Action Only pistols
• MK23
• Early USP models with joined one piece catch, control latch or models that have the short catch that stops the hammer rather than spur. These older versions are rare and usually easily identified because they lack the rubber coating on the hammer thumb stud.

The SIG P-Series Dual Adjustable Straight Trigger is the straight-faced version of our legendary curved P-Series Dual Adjustable Trigger. This trigger includes over travel and pre-travel adjustability. (Adjustable for double action slack and single action over travel.)

The optimized trigger face pressure-wall angle provides for outstanding single action sear release and positive, ultra-fast reset control. The ergonomics provides superior double action leverage and control.

Dual Adjustable Straight Trigger Details

This trigger is machined from tough steel. The trigger is carefully heat treated and finished in black oxide. Tight pin hole tolerances assure smooth, solid function. Guaranteed for life against defects in materials or workmanship.

Made with love, supplied with a hex key.

The trigger weight is about .83 ounces (23.45 grams)

Fit Guide

The trigger is designed to fit both current and older model traditional double action (DA/SA/decocker) P-Series pistols, including

• X5 All-Round
• P220 (see exceptions below)
• P226
• P228
• P229
• P227 and others

These triggers are approximately 10mm wide. At this time, we are not suggesting this trigger for guns equipped with the DAK trigger system.

This trigger may not be fully compatible with California compliant or similar P-series pistol models equipped with a magazine disconnector, and Grayguns urges caution. We do not recommend deactivating any mechanical safety device.

The Grayguns DA/SA triggers will not fit SIG Pro, P225 / P6, P239, West German P220s, or most SAO models. Most of these triggers are a narrower 8mm width

Intended to be installed by a qualified Sig Sauer armorer or gunsmith

The Grayguns proprietary enhanced leverage geometry reduces pull weight approximately 25 percent without compromising reliability or factory safety values. The trigger is dual-adjustable for pre and over-travel, which is what you’d expect from the Industry Leader, GGI.

Each Grayguns enhanced-geometry trigger bar is micro polished for superior smoothness and perfectly timed function. This is the Hybrid trigger shoe.

The trigger kit is engineered to provide several key benefits:

• Reduces the pull weight of double and single action without the need for spring replacements.
• Reduced over-travel
• Reduced pre-travel
• Maintains all factory safety functions.

The kit is 100 percent American made from precision machined heat treated tool steel.

100% American made from precision machined heat treated tool steel, then hand finished and treated with tungsten DLC for unlimited service life.

This kit is compatible with P226/229/228 pistols that have the larger DAK-capable frame window cut.

This can only be purchased as a complete system and REQUIRES the trigger AND the trigger bar in order to function.

The Grayguns custom-designed Strut System fully supports the main spring, reducing friction, spring bowing and fatigue. The design eliminates the typical double action “crunch” felt in OEM pistols. This full system also includes our custom P-Series Master Spring Set, to help reduce your pull weight for full tuning options.

The SIG P-Series Fat Custom Strut System was designed by Bruce Gray to help bring another Grayguns custom gunsmithing service to the drop in parts market.

For more than 40 years Bruce has been modifying factory struts to eliminate the typical double action crunch caused by the sharp edges and tip of the strut.

In his new design, the fat strut fully supports the main spring which reduces friction, spring bowing, and fatigue. The struts are cut using a precision EDM process, hand finished, and heat treated to the proper hardness. Paired with the upgraded strut, is a durable seat machined in-house out of aircraft grade aluminum and anodized. These struts are indestructible and guaranteed for life.

This full system also includes our custom P-Series Master Spring Set, to help reduce your pull weight for full tuning options. Includes 17 pound spring (red) and 19 pound spring (blue).

Fit Guide

The system is compatible with the E2 style grips, as well as most older style grips. The system fits most of the following SIG DA/SA pistol variants:

• P226
• P228
• P229
• P225-A
• P227

In some cases professional fitting will be required by a trained, qualified armorer/gunsmith who is very familiar with the pistol’s action.

Grayguns introduces the P365AST Straight Trigger. Our team’s goal to optimize length of pull and reduce over travel, while keeping the toe of the trigger no more forward than the original starting position. We succeeded in that goal and more. This UpGray’d trigger now breaks at 90 degrees giving the operator a clean index while providing a wider area of finger placement. This trigger has a new over travel screw that can be adjusted to take out all of your wasted over travel.

Made in the USA from solid bar-stock steel, this trigger is backed by the Grayguns lifetime warranty. The Grayguns P365ST Straight Trigger sets the standard by which all others are judged.

The custom-designed Grayguns Short Reset Trigger (SRT) Kit incorporates SIG Sauer’s Safety Lever – with permission – and is designed to provide a smooth, short action reset in a drop in kit. The kit reduces the trigger reset travel by about 70 percent*, when using one of our dual adjustable triggers.

The really special part of this kit is the Bruce Gray designed custom sear. It is a bar-stock steel component, classically machined, painstakingly cut and inspected. The sear is hand-finished for the best angle of engagement and release with the factory hammer. The part is heat treated and stoned to provide a very smooth surface. We follow up with a baked-in nickel PTFE coating for a smooth release and outstanding durability.

User feedback indicates many shooters find their follow-up shots are quicker and more accurate with the Grayguns SRT Kit installed in their SIG DA/SA pistols. (See our Fit Guide below.)

Our Grayguns SRT Kit includes:

• Bruce Gray designed bar-stock custom sear
• SIG Sauer safety lever
• Two, 19 pound mainsprings*

Bruce Gray combined the best of both worlds when he designed what we know as the hybrid trigger.

The unique face allows the shooter can take advantage of finger placement lower on the face, with the comfort of a traditional curved face. This hybrid design reduces trigger weight while preserving all mechanical safety values.
