The NDZ Performance Enhanced Safety is a precision-machined upgrade for Mossberg 12 and 20 gauge shotguns. Crafted from durable 6061-T6 billet aluminum and finished in black hardcoat anodizing, it replaces the factory part with a stronger, more ergonomic design. The improved ridges offer a secure, natural feel for faster and more confident engagement. Designed for a direct fit on models 88, 500, 590, 590A1, 835, and 940, this safety delivers better control, durability, and performance.
