C&H PLT SIG P320 RX/AXG TO HOLO EPS

Description

The C&H Precision V4 adapter plate is built for SIG P320 owners who run a factory RX, Pro Series, or AXG slide and want to mount a Holosun EPS or EPS Carry without sending the slide out for milling. The plate occupies the existing factory optic cut, so the slide stays intact and the rear sight is retained — a meaningful consideration for anyone who wants a co-witness backup or plans to rotate the pistol between optic and iron-sight configurations.

C&H machines the plate from 6061 aluminum and finishes it with a MIL-SPEC Type III hard anodize, which adds surface hardness without adding meaningful weight. The mounting hardware is stainless steel. Because the EPS and EPS Carry share the same footprint, a single plate covers both optic sizes, giving you flexibility if you later decide to swap between the full-size and compact versions of that optic family.

Fit on this type of plate is determined by the tolerance stack between the slide cut, the plate itself, and the optic. C&H recommends dry-fitting all components before final installation, which is worth taking seriously — the plate is machined to tight dimensions and any variation in your specific slide or optic will surface during a dry fit rather than under torque. Included hardware is three M4 × 10mm socket-head screws. The package is complete as shipped; no additional hardware is needed to mount the plate to the slide.

Compatible models span a wide range of the P320 family, including the AXG Legion, AXG Pro, XFive, XFull, XCompact, Spectre Comp, and XTen variants, among others. If your P320 left the factory with a rear optic cut in the RX or Pro Series configuration, this plate is designed to fill it.
