Grayguns SIG P-Series DA/SA Enhanced Leverage System, DAK, Hybrid, NIPTFE

SIG Enhanced Leverage System – P226, P229 & P228

The Enhanced Leverage System (ELS) – with options for a Curved, Straight or Hybrid Trigger – features dual adjustability for over-travel and double-action pre-travel. The trigger kit reduces double-action and single-action pull weights. This SIG P226 trigger upgrade replaces the factory leverage bar geometry. You will experience dramatically improved pull characteristics without changing springs or spring weight.

This system consists of our proprietary trigger options with enhanced geometry features mated to a custom-designed trigger bar. In addition, multiple drop-in options are available to tune your action for your specific requirements.

The ELS is not designed to reduce trigger reset, as different components are involved.

SIG P226 Trigger Upgrade Compatibility (P226, P229, P228, P220) & Fit Guide

The ELS can only be purchased as a complete system and requires the trigger and trigger bar to function. The trigger bar is incompatible with our stand-alone P-Series Dual Adjustable Straight or Curved Triggers.

You or a qualified armorer can install the Enhanced Leverage System Straight Optimized Trigger as a drop-in kit. The ELS will fit the classic P-series SIG Sauer DA/SA or DAO pistols, including:

• P226
• P229
• P228

Our kit is not yet compatible with the P226 XCarry Legion, P226 X Legion or P226 Legion. An additional plate will be required, and we are in the research and development phase for this part as of July 2026.

The 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.

This kit will not work with DAK trigger systems. The DAK references above are specific to the window frame cut, not the DAK trigger system.

The Enhanced Leverage System is not compatible with Single Action Only pistols, which include the XFIVE series of pistols.

Finishes

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

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.

Enhanced Leverage System Technical Specifications

The Grayguns proprietary enhanced leverage geometry reduces pull weight by approximately 25 percent without compromising reliability or factory safety values

We micro-polish each enhanced-geometry trigger bar for superior smoothness and perfectly timed function.

Engineered to provide several key benefits:

• Reduces the pull weight of double and single action without spring replacements.
• Adjustable over-travel screw to fine-tune and reduce over-travel
• Adjustable pre-travel screw to fine-tune and reduce pre-travel
• Maintains all factory safety functions.

Grayguns uses precision-cut heat-treated tool steel, and the kit is 100 percent American-made. We hand-finished each part to ensure the quality you have come to expect from Grayguns.

Important Version Information

Due to different window frame cuts, you must inspect the frame of your P226, P229, or P228 DA/SA pistol to determine which version to order.

• P226, P229, and P228 pistols with DAK-compatible frame window cut
• P226, P229, and P228 pistols with non-DAK compatible frame window cut

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.
