Wilson Combat Grip Module For Sig P320 Full Size No Manual Safety Green

The Wilson Combat Grip Module for Sig P320 Full Size offers a complete ergonomic overhaul of your carry or competition pistol. This full-size polymer grip frame replaces your factory P320 grip module entirely, bringing together years of refinement from professional shooters and tactical trainers into a single, purposeful redesign. The result is a handgun that feels custom-built rather than mass-produced—with dramatically improved control and pointing characteristics right out of the box.

What sets this grip module apart is its laser focus on the mechanics of fast, accurate shooting. The high-cut 1911-style beavertail eliminates that hollow gap above the backstrap, giving you a seamless grip that reduces muzzle climb and lets you shoot flatter and faster. The undercut front-strap brings your hand higher on the gun, while the reshaped trigger guard geometry lets you achieve a higher overall grip—critical for recoil management in defensive or competitive scenarios. An oversized magwell speeds up reloads without requiring ammunition changes, and it's designed to work with modern SIG factory basepads.

Texture and control are engineered throughout. Wilson Combat's signature Starburst grip pattern wraps the sides of the frame with aggressive, controllable texture, while the front and backstrap feature enhanced traction that stays put even under stress or sweat. Frame serrations give your support hand's thumb or index finger positive reference points for consistent grip placement. The light rail sports angled holster cuts that keep the gun moving smoothly in and out of your holster without catching, and internal slots accommodate rod-style tungsten weights if you want to dial in the balance to your preference.

This module ships with the factory SIG-SAUER magazine release spring and lock installed, and it's compatible with all standard P320 holsters and current SIG X-Series magazines. Available in green with no manual safety, it's a no-compromise upgrade for hunters, sport shooters, and defensive pistol users who demand better ergonomics and performance from their P320.
