Slide-Integrated Expansion Chamber

Slide-integrated expansion chamber paired with 3.7" barrel reduces muzzle rise and enhances controllability. The expansion chamber vents gas during cycling—delivers faster, more accurate follow-up shots while maintaining compact P365 handling characteristics.

DH3 Custom Slide

Custom DH3 serrations and lightening cuts on stainless steel slide finished in Coyote Cerakote. Lightening cuts reduce slide mass for faster cycling characteristics. DH3 serrations provide confident manipulation under competition and training conditions.

SIG-LOC Compact Optic Ready

Optic-ready SIG-LOC compact footprint (Shield RMSc) supports seamless red-dot integration. The compact footprint accommodates micro reflex sights for fast target acquisition.

X-RAY3 Day/Night Sights

X-RAY3 Day/Night sights provide rapid target acquisition across lighting conditions. The sights co-witness with mounted optic or serve as primary aiming system. 5.5" sight radius.

Flat-Faced Striker-Fired Trigger

Flat-faced striker-fired trigger provides consistent finger placement for repeatable trigger pull. The flat face reduces perceived pull weight compared to curved triggers.

Coyote AXG Alloy Grip Module

Coyote AXG modular alloy grip module with interchangeable polymer grip panels provides a more substantial feel than standard polymer grip modules. The alloy construction adds weight for recoil management while maintaining AXG platform modularity. Grip panels are black polymer.

M1913 Accessory Rail

M1913 Picatinny accessory rail on grip module for mounting lights or lasers. The rail provides accessory flexibility without adding bulk to the slide.

Removable Magwell

Removable magwell improves reload speed without permanently altering the pistol. The magwell guides magazines during competition and training reloads.

Three Magazines Included

Ships with one 17-round and two 21-round steel magazines. Compatible with 17-, 21-, or 10-round steel magazines for adaptable capacity.

25.3 oz Loaded Weight

25.3 oz with magazine—slightly heavier than standard P365-XF DH3 due to AXG alloy grip module. The added weight improves recoil management during rapid fire.

Daniel Horner Collaboration

Built in collaboration with Daniel Horner—elite-level competitive shooter. The DH3 designation reflects Horner's input on features, serrations, lightening cuts, and performance characteristics for competition-driven shooters. The Sig Sauer P365-DH3 AXG delivers competition-focused full-size performance—slide expansion chamber with coyote AXG alloy grip and optic-ready capability for 9mm speed and control.
