SIG Sauer® P365XF DH3 9×19

The SIG SAUER P365XF DH3 in 9×19 was developed in collaboration with professional shooter Daniel Horner and builds on the proven P365 platform in a full-performance configuration. The slide-integrated expansion chamber combined with a 3.7" barrel reduces muzzle rise and enhances control during rapid fire. A lightweight yet full-size grip module with a 1913 Picatinny rail and removable magwell gives the pistol a competition-oriented character without unnecessary weight. The DH3 model brings together speed, control, and modern features in a compact package.

Integrated Expansion Chamber

The slide incorporates an integrated expansion chamber paired with the 3.7" barrel. This system is engineered to reduce muzzle rise and improve controllability during dynamic shooting. The design maintains the balance typical of the P365 platform while supporting consistent performance in rapid follow-up shots.

DH3 Slide Configuration

The stainless steel slide features distinctive DH3 serrations and lightening cuts. A Coyote Cerakote finish enhances surface durability while giving the pistol its characteristic appearance. The configuration is both functional and visually distinct from standard P365 variants.

Optics Interface and Sights

The slide is optics-ready using the SIG-LOC compact footprint for direct mounting of compatible red dot sights. The pistol is equipped with XRAY3 day/night sights, providing reliable visibility in varied lighting conditions. When used with a ROMEO-X red dot sight, the iron sights remain functional for co-witness capability.

Frame and Ergonomics

The Coyote polymer grip module features a standard 1913 Picatinny rail for accessory mounting and a removable magwell to support faster reloads. Interchangeable backstraps (small, medium, and large) allow the shooter to tailor the grip to individual preference. The construction remains lightweight while offering full control and shootability.

Magazines and Compatibility

The model is compatible with steel magazines in 17-, 21-, or 10-round configurations, depending on manufacturer specification. This flexibility makes the platform suitable for competition, training, or regulated-capacity environments.
