Sig Sauer P320 X-Series Full-Size Large Grip Module, Coyote

Description

This large grip module transforms your P320 or P250 fire control unit into a full-size X-Series configuration with professional-grade ergonomics. The coyote polymer construction delivers durability while the extended beavertail and high undercut trigger guard work together to position your hand higher on the frame for better recoil management and faster follow-up shots.

What Makes the X-Series Grip Module Different

The X-Series design improves upon the standard P320 frame with a refined grip angle and contours that promote a natural, consistent hand position. These ergonomic improvements make a real difference when you're putting rounds downrange, whether at the range or in practical shooting scenarios. The frame also maintains magwell and weight compatibility, so you can add accessories and upgrades later if you want.

Full-Size, Large Profile

Designed for the full-size P320 platform with a 4.70-inch barrel length, this large-circumference grip works well for shooters who prefer a more substantial hand fill. You'll need to pair it with appropriate full-size 9mm, .40 S&W, or .357 SIG slides and barrels to complete the build. The module itself is pure polymer for weight savings and durability.

Installation and Compatibility

Swapping your fire control unit into this grip module is straightforward. Just remove your current FCU and install it into the X-Series frame. One thing to keep in mind: X-Series grip modules work with magazines featuring the SIG mark on the baseplate, not the older style marked "SIG SAUER." The extended magwell and internal weight aren't included but are available separately if you want to add them.
