Description
The Ruger RXM 9mm FDE Threaded Tritium is a striker-fired 9mm pistol with a 4.5 inch threaded barrel, a Magpul Flat Dark Earth frame, an FDE Cerakote slide and a tritium front sight. It holds 15+1 rounds, is cut for RMR and RMSc pattern optics and ships with two magazines.

Ruger RXM 9mm FDE Threaded Tritium Overview
The RXM is the result of a partnership between Ruger and Magpul, and it is built around a removable stainless steel fire control unit, the serialized part, that can move between different grip modules. This special run version pairs a Magpul Flat Dark Earth frame with an FDE Cerakote slide for a clean, monochrome look. The frame has a low-profile flared magwell, a magazine release scallop and an extended magazine catch, and it uses the Magpul Enhanced Handgun grip texture.
5 inch barrel is threaded 1/2×28 with a 1:10 twist, so it is ready for a suppressor or compensator. Sights are a tritium front at co-witness height and a steel drift adjustable rear, and the slide is cut for RMR and RMSc pattern red dots. A flat-faced trigger, undercut trigger guard and beavertail help with a high, consistent grip. 65 inches overall.
Modular by Design
Because the fire control unit is the serialized part, the RXM can grow with you. Magpul grip modules and other slide and barrel options let you change the size and setup of the pistol without buying a new firearm.

Optic and Suppressor Ready
The RMR and RMSc optic cut and co-witness tritium front sight make it easy to add a red dot while keeping a usable iron sight backup. The threaded barrel accepts a suppressor or compensator; suppressors are NFA items and require an approved ATF Form 4 and state legality.
Carry and Holsters
The RXM is based on a popular double-stack 9mm footprint, so holster support is good and growing. Choose a holster cut for your optic and, if you add one, your weapon light, and practice your draw with an unloaded pistol.
Practice and Training
Regular practice builds confidence and safe handling. Start at close range, focus on sight alignment and a smooth trigger press, and work back as your groups tighten. Dry fire with snap caps at home to improve your trigger control between range trips.
Choosing Ammunition
Try several brands and bullet weights to see what feeds reliably and groups best in your handgun. Use quality full metal jacket loads for practice and proven hollow points for defense, and confirm reliable function with your defensive load before carrying it.
Care and Maintenance
Clean the barrel, slide or cylinder and frame after shooting, apply a light coat of quality lubricant to moving parts, and store the handgun unloaded in a locked case or safe away from children.
Safe Storage
Store handguns unloaded in a locked safe, lockbox or with a cable lock, and keep ammunition separate when children are in the home. Quick access safes keep a defensive handgun secure but available. Teach everyone in the household basic firearm safety rules.
Recommended Accessories
A quality holster, spare magazines, eye and ear protection and a cleaning kit round out any handgun purchase. For defensive use, add a weapon light and practice drawing safely from your holster with an unloaded gun before carrying.
