SIG Sauer M17X-9-RX | 9mm | 4.7 in | ROMEO-M17

The SIG Sauer M17X-9-RX is a full-size service-frame pistol chambered in 9mm Luger with a 4.7 inch barrel, delivered with a factory-mounted ROMEO‑M17 red dot. It pairs the M17 platform ergonomics and magazine capacity with XSeries upgrades such as an X‑Series flat trigger and a Coyote X‑Carry grip module that includes a magwell extension. This configuration is suited for duty/service use and precision training or competition at the range. For optics, the factory‑installed ROMEO‑M17 is an appropriate red‑dot option for this pistol and is included on the slide.
