SIG Sauer® P365 DH3 AXG Pistol – 9×19

The SIG Sauer^® P365 DH3 AXG in 9×19 was developed in collaboration with professional shooter Daniel Horner and builds upon the proven P365 AXG platform. It combines a 3.7-inch barrel with an integrated slide expansion chamber designed to reduce muzzle rise and improve control during rapid fire. The metal AXG (Alloy XSeries Grip) module in Coyote Cerakote provides enhanced rigidity and balance while maintaining the compact dimensions characteristic of the P365 series. The DH3 AXG blends competition-oriented features with a configuration suitable for duty and defensive applications.

Integrated Slide Expansion Chamber

The slide incorporates an integrated expansion chamber system paired with a 3.7-inch barrel. This design redirects propellant gases to mitigate muzzle rise and support faster shot-to-shot recovery. The configuration preserves the compact footprint of the P365 platform while enhancing controllability during dynamic shooting.

DH3 Slide Design

The stainless steel slide features distinctive DH3 serrations and lightening cuts. A durable Coyote Cerakote finish increases corrosion resistance while providing the model’s signature appearance. The slide geometry balances weight reduction with structural strength.

AXG Metal Grip Module

The AXG (Alloy XSeries Grip) module is manufactured from lightweight aluminum alloy and includes a 1913 Picatinny accessory rail. Interchangeable polymer grip panels allow ergonomic customization, while the removable magwell facilitates faster reloads. The metal grip module enhances recoil control and overall balance compared to standard polymer frames.

Optics and Sights

The slide is optics-ready with a Shield RMSc footprint, allowing direct mounting of compatible micro red dot sights. The pistol is equipped with XRAY3 day/night sights for rapid sight acquisition in varying light conditions. The platform supports seamless integration of modern pistol optics.

Magazine Compatibility

The P365 DH3 AXG is compatible with steel P365 XMACRO-pattern magazines in capacities of 17, 21, or 10 rounds depending on configuration and market requirements. Magazine inclusion may vary according to manufacturer specifications.
