Overview

The Polymer80 PF320PTEX Grip Module for SIG SAUER P320 is purpose-built for the P320 platform, offering a drop-in fit for all standard P320 fire control units. It is machined from a high-impact polymer that holds up to holster wear and heavy range use. The key feature here is the PTEX texture pattern, which provides a positive, grippy surface without being overly abrasive against skin or clothing. It keeps your hand locked in during fast strings of fire. This module also includes an integral trigger guard undercut and a beavertail that sits high, promoting a consistent master grip on every draw. It is compatible with standard P320 magazines, slide releases, and takedown levers, so you won’t need to chase new parts.

Features & Specs

This module was tested on the range to ensure it locks up tight with the FCU and maintains zero on optics. The geometry is slightly more vertical in the grip angle compared to some factory modules, which helps with natural point of aim for most shooters. Below are the core specifications and what you can expect out of the box.

• Drop-in fit for all standard SIG SAUER P320 fire control units and slides; no fitting or modification required
• Aggressive PTEX texture on the frontstrap, backstrap, and side panels for maximum purchase under wet or sweaty conditions
• Integral trigger guard undercut and high beavertail to prevent slide bite and allow a higher grip position

The module also features an interchangeable backstrap system (sold separately if needed) to accommodate different hand sizes. The magazine well is slightly flared for faster reloads, and the dust cover is cut to clear most threaded barrels and compensators. Overall weight is light enough for daily carry but rigid enough for competition use.

Who It Is For

This Polymer80 PF320PTEX Grip Module for SIG SAUER P320 is ideal for the hands-on shooter who prefers to tune their pistol to their hand. It is a great choice for competition shooters who want a more aggressive texture than factory options, or for concealed carriers who need a secure grip when drawing from concealment. It also serves builders who are assembling a P320 from an 80% FCU, as it provides a complete grip platform with no additional finishing work. If you found the factory SIG module too slick or the grip angle too steep, this module offers a tangible improvement without requiring a gunsmith.
