Sig Sauer M17X9RX M17X w/Optic Full Size Frame 9mm Luger 21+1 4.70" Black Barrel, Coyote PVD Optic Ready/Serrated Stainless Steel Slide & Polymer Frame w/Beavertail & Picatinny Rail, Sig ROMEOM17

The Sig Sauer M17X 9mm is a full-size, optics-ready striker-fired pistol built on the platform trusted by the U.S. military. This is the next generation of duty/carry performance: it ships with a factory-installed ROMEO M17 red dot sight, a coyote-tan modular polymer grip module, and three 21-round steel magazines. If you want a modern, capable full-size 9mm that's ready for the red dot out of the box—without the assembly hassle or expense—the M17X eliminates the guesswork.

The M17X balances professional-grade reliability with shooter-friendly features. The stainless steel slide wears a coyote PVD finish for durability and a contemporary look. Its carbon steel barrel measures 4.7 inches, giving you a practical balance of velocity and shootability in a full-size frame. The striker-fired action is paired with an X-Series flat blade trigger designed to deliver better tactile feedback and consistency. A beavertail grip helps you get a high, secure grip, and aggressive stippling on the coyote-tan grip module keeps your hand locked in place under recoil. The M1913 Picatinny rail lets you mount a light, laser, or other accessories.

The ROMEO M17 red dot features an aspheric glass lens for zero distortion, a fully sealed and enclosed design to keep dust and moisture out, and ruggedized aluminum construction. It's pre-mounted and zeroed at the factory—mount it and shoot. The optic footprint is Sig's SIG-LOC pattern, designed for the M17/M18 MHS platform. Grip modules are swappable, so you can tune the ergonomics to your hand if needed. At 33 ounces loaded, the M17X carries like a modern duty gun: substantial and controlable, not featherweight.

This is a gun for serious shooters who value out-of-the-box capability, combat-proven design, and the flexibility to evolve their setup. Whether you're training for defensive carry, duty use, or the range, the M17X arrives fully equipped and ready to perform.
