Rival Arms SLD Sig320 Full A1 Doc B RA10P301A

The Rival Arms SLD Sig320 Full A1 DOC B grip module is a straightforward, high-performance upgrade for Sig Sauer P320 Full A1 owners who want improved ergonomics and faster reloads without breaking the bank. Built from high-strength polymer, this module replaces the factory frame with a tougher, more wear-resistant chassis that stands up to heavy use and rough handling. The textured grip pattern delivers a confident purchase whether you’re running drills at the range or carrying daily, and the aggressive checkering won’t let your hand slip when things get hot.

What sets this module apart is the integrated magwell. Molded for smooth mag transitions, the magwell funnels magazines into place for faster, more reliable reloads—an advantage in competition, training, and defensive work alike. The magwell is proportioned to aid speed without getting in the way of a natural grip, so you’ll notice quicker reloads without sacrificing control or concealability.

Rival Arms engineered this module to be a drop-in replacement for all Sig320 Full A1 pistols and to remain compatible with factory magazines, making the swap painless and cost-effective. Installation requires basic tools and a working knowledge of pistol assembly, but it doesn’t demand gunsmithing or permanent modifications to your firearm. That accessibility means you can upgrade your pistol’s handling in minutes and get back to training.

Durability and feel were front and center in the design. The polymer formulation resists impacts and environmental wear better than OEM polymer in many cases, and the reinforced internal geometry maintains proper alignment with slide rails and controls for consistent, repeatable operation. Control placements are intuitive and kept in factory positions so your reload and manipulation muscles don’t have to relearn new ergonomics.

This module gives you practical, combat-proven features without unnecessary bells and whistles: a rugged polymer body for long life, a textured grip that anchors your hand, and a built-in magwell for faster reloads. It’s a smart upgrade for serious shooters who want tangible performance improvements for duty, competition, or everyday use.

Pick the Rival Arms SLD Sig320 Full A1 DOC B if you want a dependable, performance-oriented grip module that enhances reload speed and grip control while staying compatible with your Sig320 Full A1 magazines and parts.
