Sig Sauer P365-XFive DH3 Handgun 9mm Luger 21(2) & 17(1)rd Magazines 3.7" Barrel Coyote Finish AXG Grip Xray Sights

The Sig Sauer P365-XFive DH3 is a full-size 9mm striker-fired handgun built in collaboration with competition shooter Daniel Horner. It blends the proven P365 AXG platform with purpose-built performance upgrades—a slide-integrated expansion chamber paired with a 3.7" barrel designed to tame muzzle rise and let you nail faster, more controlled follow-up shots without sacrificing the compact handling that makes the P365 family so reliable. Whether you're training hard at the range or carrying duty-ready, this is a serious upgrade over the standard compact.

The DH3 wears a stainless steel slide finished in Coyote Cerakote, dressed up with custom DH3 serrations and strategic lightening cuts that aren't just for show—they reduce weight and improve control. X-RAY3 day/night sights come standard, so you can acquire your target fast in any light. The whole package is optic-ready with a SIG-LOC compact footprint, meaning you can mount modern red-dot sights without fuss. The Coyote AXG grip module is equally adaptable: it includes a 1913 Picatinny rail for lights or lasers, interchangeable polymer grip panels to dial in your fit, and a removable magwell for confident reloads.

You get a solid foundation right out of the box: two 21-round magazines and one 17-round magazine in stainless steel, plus the versatility to run 10-round magazines if needed. At 7.2" overall length and 5.2" height, it balances full-size ergonomics with real-world carry and handling. The 5.5" sight radius, flat-faced striker trigger, and no manual safety design keep the focus on speed and repeatability. This is a gun that rewards practice and delivers when it matters.
