The Trijicon RMR Mount AC32087 is the purpose-built SRO and RMR adapter plate designed specifically for the Sig Sauer P320 M17 handgun - the factory-correct mounting solution that ensures a perfect fit between the Trijicon RMR or SRO micro red dot and the P320 M17's optics-ready slide without any gunsmithing, slide milling, or permanent modification required. The SIG Sauer P320 M17 Mount AC32087 is specifically dimensioned and engineered for the P320 M17 slide's optic mounting footprint - a purpose-built fit that ensures proper alignment, proper dimensional engagement, and reliable zero retention that a military-adopted and duty-carry pistol platform demands from a red dot mounting solution. The P320 M17 is the commercial variant of the U. S. Army's M17 service pistol, and owners who run this platform for duty, defensive carry, and competition deserve mounting hardware that matches the platform's serious operational character. The Trijicon RMR/SRO Pistol Mount AC32087 accommodates both the Trijicon RMR and the SRO micro red dot sight - giving P320 M17 owners the flexibility to choose the specific Trijicon optic that best fits their duty, defensive carry, or competition shooting application. The RMR delivers the enclosed emitter durability that hard-duty use demands, while the SRO's larger window benefits competition- and training-focused shooters who prioritize target acquisition speed and sight-picture clarity. The red dot mount AC32087 installs directly into the P320 M17 slide's factory optic mounting location - a clean, integrated installation that maintains the pistol's overall profile without the added bulk that rail adapter solutions introduce. Correct dimensional fitment ensures reliable zero retention through sustained training and duty recoil cycles.
