Ruger RXM 9mm 4" 17rd Gray Aimpoint COA Pistol

The RXM COA Edition is the version of the Ruger and Magpul pistol that comes with the red dot already installed. Aimpoint's COA sits in an A-CUT pocket milled into the slide, so the sight body locks mechanically into the steel instead of riding on an adapter plate. The 3.5 MOA dot runs for years on a single battery, and the closed emitter housing keeps rain, lint and holster grit off the lens, which is the failure mode that kills open reflex sights on carry guns.

Underneath the optic the gun is a full RXM. The serialized chassis lifts out of the grip module, so the polymer frame counts as a part and can be swapped for a different size or color later. This one wears a Stealth Gray Magpul Enhanced Handgun Grip against a black slide, a quieter look than all black without going loud. Barrel length is 4" and each of the two included Magpul PMAG 17 GL9 magazines holds 17rd. Steel co-witness height sights sit under the dot so there is still a usable aiming reference if the optic goes dark. The trigger is flat faced with a short reset, the frame takes a light on the accessory rail, and magazines follow the Glock 19 pattern, so holsters and spare mags are easy to find.
