Stand-Out Features
I’ve mounted this plate on three different P320s during testing. The machining is precise – no wiggle when torqued to spec (15 in-lbs). Our customers report it holds zero better than some plates costing twice as much. The anodizing is consistent, with no tool marks visible under magnification.
Strengths and Weaknesses
✅ Precision fit – In our testing, the RMSc cutout required no filing for Holosun 407K/507K optics ❌ Limited availability – Frequently sells out due to demand Buy if: You need a bombproof RMSc mount for your P320 that won’t break the bank. I recommend this to customers who compete with optics-equipped pistols. Skip if: You require multi-optic compatibility or need immediate shipping during peak seasons. Yes – the EPS Carry uses the RMSc footprint. We’ve installed this combination for 12 customers with zero fitment issues reported. Jovinogunshop carries the Alpha Foxtrot plate with same-day shipping from our Rapid City warehouse. In side-by-side testing, we found the Hales plate has tighter tolerances than the CHPWS QLS model, though both are quality options. No – we recommend using blue Loctite 242 (not included) on the mounting screws. Less than 2% across 39 sales – most returns were from customers ordering the wrong footprint. Depends on your slide cut. On our test P320 AXG, it provided lower 1/3 co-witness with factory sights. The Hales plate is 0.02″ thicker than Sig’s factory option, reducing flex during recoil based on our range testing. Last updated: May 2026
