Outerimpact Modular Red Dot Adapter for SIG P320 - M17 & X5 Legion

• Multi-footprint compatibility: The adapter accepts several popular red dot mounting standards, making it easier to fit different pistol optics without committing to a permanent slide cut.
• 7075-T6 aluminum construction: The plate combines low weight with the strength needed for reciprocating-slide use, helping the optic stay secure under repeated recoil.
• Steel alignment system: Steel alignment pins and steel interface parts help keep the sight properly indexed, which supports repeatable mounting and more dependable zero retention.
• Low-profile pistol fit: Built for the SIG P320-M17 civilian version and X5 Legion pattern, the mount adds red dot capability while keeping added bulk and height under control.
• Complete mounting hardware included: Supplied screws and installation hardware simplify setup and make it easier to match the adapter to compatible optic footprints.

About the - Series

Outer Impact's Modular Red Dot Adapter line is built around a simple idea: give shooters a way to mount different pistol and rifle optics without dedicating a firearm to one permanent footprint. Within the brand's firearm-accessory range, the series focuses on modular red dot mounting platforms for users who want flexibility across multiple sight standards and firearm models. That makes the line especially relevant for shooters comparing optic formats, replacing an existing sight, or setting up a handgun for competition, range use, or defensive carry without slide machining.

The series is known for using 7075-T6 aluminum plates, black anodized finishes, and a hardware layout that incorporates steel alignment pins with Weaver-style screws. In practice, that design approach aims to balance low weight with the mechanical stability needed on reciprocating slides and other hard-use platforms. Across the range, the distinguishing characteristic is not one specific footprint but the ability to bridge several of them through one adapter system, giving the shooter more freedom when selecting a red dot sight.

About the Outerimpact Modular Red Dot Adapter for SIG P320 - M17 & X5 Legion

The Outerimpact Modular Red Dot Adapter for SIG P320 - M17 & X5 Legion is designed for shooters who want to add a pistol red dot to a compatible SIG P320-M17 civilian version, M18, or X-5 Legion pattern slide without moving to a dedicated custom optic cut. Its main advantage is flexibility: one adapter supports multiple mounting standards, so the pistol can be set up around the optic that best suits the role, whether that means a compact carry-style sight or a larger window for range and competition use.

The plate is machined from 7075 aircraft aluminum and finished in black anodizing, a combination that keeps weight modest while providing the rigidity expected from a slide-mounted interface. Outer Impact also uses steel alignment pins and Weaver T-10 Torx screws to help the optic seat consistently and stay properly indexed under recoil. That matters on a handgun mount, where even small shifts can affect zero or create uneven stress on the sight body.

At 50.80 mm in length with a 0 MOA inclination, the adapter keeps the setup straightforward and neutral, with no built-in cant to complicate pistol zeroing. Compatibility with footprints such as Docter, Trijicon RMR, Shield RMS, Leupold DeltaPoint Pro, C-More RTS, and Holosun 407K/507K makes this mount particularly useful for shooters who want broad optic choice from a single handgun-specific mounting solution.
