$81.88
The Sig Sauer P320 Grip Module X-Series Compact in Coyote is your ticket to customizing one of the most modular pistols on the market. If you've got a P320 or P250 firing control unit and want to adapt it to a compact platform, this medium-size grip module is the foundation you need. It's designed to work with compact and sub-compact slides in 9mm Luger, .40 S&W, or .357 Sig—giving you flexibility to build the exact gun you want without buying a whole new pistol.
The X-Series grip module comes in Coyote polymer, a tough, durable finish that handles daily use and range sessions. The medium size strikes a balance for shooters who want a compact footprint without sacrificing control and comfort. This module fits P320 barrels and slides measuring 3.60" and 3.90", making it ideal for those who prefer a shorter sight radius and faster handling compared to full-size guns.
One important note: this grip module is built for compact and sub-compact slides only—it's not designed for full-size P320 models, and won't properly cover a full-size dust cover. Also, make sure your magazines have the SIG Mark baseplate, not the "SIG SAUER" text baseplate, for reliable compatibility with the X-Series platform.
Whether you're building a backup gun, a dedicated competition rig, or just exploring the modular P320 ecosystem, this grip module gives you the foundation to do it right. Combine it with your choice of compact slide and barrel to create a pistol that fits your mission.
