Outerimpact Modular Red Dot Adapter for SIG P320

• Multi-footprint compatibility: This adapter accepts several popular red dot mounting standards, making it easier to move between optic brands without changing the pistol or committing to a permanent slide modification.
• 7075-T6 aluminum construction: The plate is machined from a strong aircraft-grade alloy that keeps weight low while standing up to the repeated recoil forces of a reciprocating pistol slide.
• Steel alignment pins and Weaver-style screws: These parts help keep the optic properly indexed under recoil, supporting consistent zero retention and a more secure installation.
• Dovetail-based installation: The mount fits through the rear-sight dovetail, giving the shooter an optics-ready solution for a standard SIG P320 without slide machining.
• 0 MOA profile: A flat mounting angle keeps the optic in a straightforward, neutral position that suits general pistol use and simplifies sight setup.

About the - Series

Outer Impact’s Modular Red Dot Adapter line is built around a simple idea: one mounting platform should support multiple red dot footprints on firearms that were not originally dedicated to a single optic standard. In practice, that makes the series relevant to shooters who want to add a pistol or rifle optic while keeping their host platform flexible for future changes. Rather than locking the user into one sight family, the system is designed to bridge several common mounting patterns.

Across the range, the series is known for a modular layout, compact form, and hardware intended for repeated live-fire use. Outer Impact also describes the line with details such as steel alignment pins and black-finished aluminum construction, reflecting a design focus on maintaining alignment under recoil while keeping overall bulk manageable. For handgun applications especially, that modular approach is useful for testing different optic sizes and window styles before settling on a long-term setup. The result is a practical mounting family aimed at shooters who want a red dot-ready platform without giving up the option to change optics later.

About the Outerimpact Modular Red Dot Adapter for SIG P320

The Outerimpact Modular Red Dot Adapter for SIG P320 is a handgun optic mount made for shooters who want to add a red dot to a SIG P320 without machining the slide. By using a dovetail-based mounting arrangement, it provides a practical route into pistol optics for range use, defensive training, and general shooting where a slide-mounted red dot can improve target focus and speed.

What sets this model apart is its broad footprint compatibility. It supports mounting standards including Docter, Trijicon RMR, Holosun 407K/507K, Shield RMS, Leupold DeltaPoint Pro, and C-More RTS. That flexibility matters in real use because it allows the pistol to adapt to different optic sizes, window shapes, and brand preferences while keeping the same base mount on the firearm.

The mount body is made from 7075-T6 aluminum, a material choice that balances low weight with the strength needed for slide-mounted use. Outer Impact also uses steel alignment pins and Weaver T-10 Torx screws to help the optic stay properly positioned under recoil, which is important for maintaining zero and reducing movement over time. Its 0 MOA inclination keeps the setup straightforward, while the black anodized finish and compact 54.60 mm length help the adapter integrate cleanly with the pistol. This model is intended for the P320 base model and SP2022, and it is not compatible with X-5, M17, or Optics Ready P320 variants.
