Description
Purpose-built in the U.S., the Ruger RXM 9mm 10rd OR 4″ Tritium Front, Gray Magpul Grip combines modern striker-fired performance with thoughtful modularity and straightforward maintenance. Its core is a removable, serialized stainless Fire Control Insert (FCI) that drops into an interchangeable Magpul Enhanced Handgun Grip (EHG), giving end users long-term serviceability and the ability to adapt ergonomics without replacing the firearm.
For aiming solutions, the RXM uses a direct-mount optic cut that accepts popular RMR, DeltaPoint Pro (DPP), and RMSc pattern footprints—no tall plates to stack, and co-witness-height steel sights provide a usable backup. The front sight is a tritium night unit for low-light visibility; the rear is drift adjustable steel. This co-witness arrangement means you can verify your dot and maintain an immediate sight picture if the optic is removed or the window is obscured.
The pistol’s 4″ precision-rifled alloy steel barrel and through-hardened alloy steel slide are finished in black FNC nitride for durability and corrosion resistance. Overall length is 7.15″ (18.1 cm) with a slide width of approximately 1″ (25 mm), balancing concealability with controllability. Unloaded weight is 23.2 oz (657 g), keeping the package light enough for daily carry while remaining stable on the range.
Ergonomics are centered on the Stealth Gray Magpul EHG. Magpul’s texture and indexing pads help with consistent hand placement, while the low-profile, flared magazine well and trigger-guard undercut encourage a high, secure grip. The RXM also includes an extended magazine release and a raised slide stop to speed manipulations during reloads and administrative handling. A universal-pattern accessory rail supports common weapon lights and lasers.
Triggering is striker-fired with a flat face, smooth take-up, and tactile reset. Safety features include an integrated trigger safety and an internal striker blocker. There is no manual safety on this variant, reducing controls for users who prefer a simpler manual of arms. Ruger further notes that most major components are designed to operate in “Gen 3-type” pistols, aiding compatibility with many off-the-shelf holsters and accessories—useful if you already have a gear drawer built around that ecosystem.
This specific configuration—Ruger model 19401—is the 10-round, capacity-compliant model chambered in 9mm Luger. It ships with two Magpul PMAG 10 GL9 magazines and a co-branded plastic carry case. The combination of a tritium front sight, co-witness steel irons, and direct-mount optic footprints makes the Ruger RXM 9mm 10rd OR 4″ Tritium Front, Gray Magpul Grip a strong out-of-the-box choice for home defense, concealed carry in capacity-restricted jurisdictions, and range practice with or without an optic.
