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—allows for faster, more consistent follow-up shots while maintaining P365 platform balance and handling.

DH3 Custom Slide

DH3-specific serrations and lightening cuts on stainless steel slide finished in Coyote Cerakote. The lightening cuts reduce slide mass for faster cycling characteristics. Custom 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 in any lighting condition. 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 Polymer Grip Module

Coyote polymer grip module with M1913 Picatinny accessory rail for light or laser mounting. Removable magwell improves reload efficiency. Interchangeable small, medium, and large backstraps allow shooters to tailor fit and feel to preference.

Interchangeable Backstraps

Small, medium, and large backstraps included—allows customization of grip circumference without aftermarket components. The interchangeable design accommodates varied hand sizes for consistent trigger reach.

Removable Magwell

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

Three Magazines Included

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

Coyote Cerakote Finish

Coyote Cerakote on stainless steel slide and frame provides corrosion resistance with distinctive earth tone appearance. The finish coordinates with coyote polymer grip module.

22.9 oz Loaded Weight

22.9 oz with magazine in full-size configuration. The lightweight construction maintains P365 handling characteristics in full-size format.
