Replace the OEM polymer magazine floor plate in your Sig P320 with a purpose-built billet aluminum upgrade that adds strength, durability, and a clean tactical finish without changing magazine capacity or fit. Machined from 6061-T6 aircraft billet aluminum and finished in Tungsten Cerakote; this NDZ Performance floor plate gives you a slim, rock-solid alternative to stock plastic plates that stands up to daily carry, range use, and hard conditions. Aluminum floor plates provide lasting strength and repeatable function on compact and full-size magazines alike. Simple, durable, and built for carry; swap the plastic plate for a precision all-aluminum part that actually improves performance.
Why it matters: This direct-replacement base plate preserves all factory internal components and magazine capacity while adding a stiff, wear-resistant interface that won’t crack, chip, or deform like polymer. It’s an easy, practical way to improve magazine longevity and identification on duty or at the range.

- CNC machined from 6061-T6 billet aluminum for real-world durability.
- Cerakote Tungsten finish: corrosion-resistant, low-glare, and matched to rugged builds.
- Zero capacity change: retains original follower, spring, and internal parts.
- Low-profile design maintains holster and pouch compatibility.
