Trijicon® RMR® Footprint Steel Pistol Dovetail Mount – Fits SIG Sauer® Non-Adjustable Sights – RM50
The Trijicon® RMR® Footprint Steel Pistol Dovetail Mount (RM50) is a 2026-spec premium optics integration interface engineered specifically to bring high-speed red-dot capabilities to standard SIG Sauer® handguns without the extensive costs or turnaround times of custom slide milling. While modern reflex sights dramatically enhance a shooter's target acquisition velocity and low-light tracking, many classic, combat-proven SIG pistols feature solid, un-cut slides. The RM50 framework (719307609136) masterfully solves this problem, acting as a direct drop-in replacement that slides tightly into your factory rear sight notch to provide a rock-solid structural bridge for your electronic optic.
Precision-machined from a monolithic block of high-tensile solid steel in the United States and treated with a rich, wear-resistant matte black finish, the RM50 (Alternative MPN: AC32016) is designed to withstand violent slide acceleration and heavy recoil cycles. Weighing a mere 32 grams (1.13 ounces), this ultra-lean platform securely updates the slide architecture while preserving the factory balance and tracking harmonics of the handgun. The mount features parallel indexing indexing tabs built to host any miniature red dot sharing the universal Trijicon RMR/SRO footprint, including the RMR Type 2, RMR HD, SRO, and RCR closed-emitter optics. To ensure absolute electronic integrity, the kit includes a premium stainless steel sealing plate, creating a compression gas seal along the bottom battery compartment of the RMR to preserve its submersible waterproof sub-ratings during severe weather field duty. Complete with all necessary socket set screws and dedicated optic-fastening hardware, this steel dovetail platform turns classic handguns into high-efficiency, red-dot-equipped defensive assets.
Includes: (1) Trijicon RM50 Steel Pistol Mount with SIG Sauer Dovetail Base, (1) Stainless Steel RMR Sealing Plate, (2) Dovetail Socket Set Locking Screws, (2) Trijicon RMR/SRO Mounting Screws, and (1) Hex Allen Wrench Tool.
*Compatibility Note: This adapter plate is explicitly built to fit most **SIG Sauer® pistol models featuring standard, fixed (non-adjustable) rear factory sight cuts**, including the P220, P226, P229, P239, and SP2022 families. It is NOT compatible with SIG models outfitted with factory adjustable target sights, X-Frame models, or modern factory optics-ready slides (such as the P320 AXG or P365X series, which require direct-mount adapter plates rather than dovetail wedges).
Key Features
- Universal Trijicon RMR/SRO Footprint: Instantly adapts your slide to accept the Trijicon RMR Type 2, Dual-Illuminated RMR, SRO, RMR HD, and RCR reflex sights.
- Zero-Milling Dovetail Integration: Mounts securely by displacing the factory rear iron sight, eliminating the need for expensive, permanent aftermarket gunsmith milling.
- Monolithic Hardened Steel Core: Solid steel engineering prevents the indexing alignment bosses from warping or shearing off under thousands of rapid slide cycles.
- Stainless Steel Sealing Plate Included: Includes a protective metal under-layer plate that creates an unyielding moisture barrier to lock in the RMR's waterproof protection.
- Featherweight 32-Gram Frame: Low-profile, ultra-lean layout adds virtually zero parasitic weight to the top end, keeping your slide cycling paths clean and unhindered.
- Dual Mechanical Set Screws: Employs a pair of high-torque socket set screws to lock the base wedge tightly into the frame channel, preventing left-or-right windage drift.
