Chp Sig P320 Rx/pro Srs/axg Adpt Eps

Running a Holosun EPS optic on your Sig Sauer P320 RX, Pro Series, or AXG platform? The C&H Precision Weapons adapter plate solves the mounting challenge with precision engineering that reflects the company's commitment to tight tolerances and American manufacturing. This Sig P320 RX/Pro Series/AXG adapter for Holosun EPS sights bridges the gap between your slide cut and modern red dot, giving you a rock-solid platform for duty, competition, or carry setups.

C&H Precision machines every plate on HAAS CNC equipment in their Georgia shop, then subjects each one to multiple quality checks before it ships. The 6061 aluminum construction wears a MIL-SPEC Type III hard anodized finish—the same standard that protects military components. What sets this adapter apart is the stainless steel T-nut design: C&H engineered it to deliver six to seven threads of engagement, which is industry-leading grip on your optic's mounting screws. If a T-nut or any hardware ever takes a hit, you don't replace the whole plate—just swap the damaged component. That practical durability mindset is pure C&H.

The package includes the plate itself, plus all the hardware you need to mount it to your slide and attach your Holosun EPS. Whether you're building a carry gun, a range rig, or a competition pistol, this adapter handles the job without fuss or flex.
