The C&H Precision Weapons P320 X-5 M17/18 R1Pro/DPP to EPS optic mounting plate is a precision-machined adapter designed to let you run a Holosun EPS or EPS Carry red dot on your Sig Sauer P320 X-Five, M17, or M18 pistol—even if your slide is already cut for a Romeo1Pro or DPP. Built by a family-owned operation in coastal Georgia, this demo/used plate delivers the tight tolerances and durability you'd expect from a gunsmith-grade part at a fraction of new pricing.
Each plate is CNC-machined on HAAS equipment and passes multiple quality inspections before it ships. The real backbone of the design is the patented stainless steel T-Nut, which locks in with six to seven threads of engagement—significantly more than industry standard. That translates to rock-solid optic stability and zero creep under recoil. If mounting hardware ever takes a hit, every bolt and nut is replaceable; you'll never have to scrap the whole plate over a damaged screw.
The plate itself is 6061 aluminum finished in MIL-SPEC Type III hard anodize, so it'll handle hard carry, competition use, and rough conditions without degrading. Whether you're upgrading your duty weapon, setting up a backup pistol, or consolidating your red-dot ecosystem around Holosun optics, this C&H plate is a practical, no-nonsense solution. The demo/used status means cosmetic wear, but the mechanical spec is uncompromised.
| Manufacturer | C&H Precision Weapons |
| Application | Sig Sauer P320 X-Five, M17, M18 |
| Optic Compatibility | Holosun EPS / EPS Carry (converts Romeo1Pro or DPP footprint) |
| Material | 6061 aluminum |
| Finish | MIL-SPEC Type III hard anodized |
| T-Nut Material | 416 stainless steel (patented design) |
| Thread Engagement | Six to seven threads |
| Hardware | Replaceable (included and field-serviceable) |
| Condition | Demo/Used |
Yes. This adapter converts a Romeo1Pro or DPP footprint to accept a Holosun EPS or EPS Carry optic, so you can switch to the Holosun platform without a new slide cut.
You get the mounting plate, two M3 screws (for slide installation), two 4-40 screws (for optic mounting), and two 416 stainless steel T-Nuts.
Yes. All mounting hardware is replaceable, so if a screw or T-Nut is damaged, you can source and install a new one without buying a new plate.
The plate is in used or demonstration condition, which may include minor cosmetic wear. The mechanical tolerances and function are unaffected.
