Sig Sauer M18X 9mm 3.9in Pistol with ROMEO-M17 Red Dot and SIGLITE Night Sights — New

The M18 is the compact sidearm the US military adopted, and this is the X configuration in black with the optic already done for you — a factory-mounted ROMEO-M17 enclosed reflex sight over SIGLITE tritium night sights, on the modular Polymer X-Grip. Striker fired, 3.9-inch barrel, 7.2 inches overall.

Buying the optic separately and having it mounted is most of the gap between this and a plain M18, which is the thing worth weighing if you are comparing listings. Here it arrives fitted, sighted and co-witnessed with the irons.

In stock at my distributor and ordered in on purchase — typically a few business days to arrive, then transferred in person here in Avondale, Arizona with no shipping or transfer fee to you.

The Optic Is The Value

The ROMEO-M17 is a fully enclosed, sealed reflex sight in a ruggedised alloy housing — the enclosed design is what keeps debris out of the emitter, which is the usual failure mode for an open red dot carried daily. It ships factory mounted. The SIGLITE night sights sit below it and remain usable on their own if the optic is ever off the gun.

Modular X-Grip Fire Control

The P320 platform puts the serialized fire control unit inside a grip module you can change, so the pistol can be resized rather than replaced. This one comes with the Polymer X-Grip module, the more aggressively textured competition-style grip rather than the standard issue one.
