Sig Sauer P320 XSeries Carry Large Grip Module Black

Description

The Sig Sauer P320 XSeries Carry Large Grip Module gives you a full-featured factory option for upgrading or customizing your P320 build. Drop your firing control unit into this grip module assembly and you've got a complete P320 Carry in the large circumference size, which pairs with 17-round magazines and works with carry or full-size slides.

This is the same grip module design you'll find on factory XSeries P320s, featuring the extended beavertail and high undercut trigger guard that Sig introduced to promote a higher grip position and improved recoil control. The integrated magwell speeds up reloads during range sessions or training. You get all the ergonomic benefits of the XSeries line in a standalone module without the full pistol price tag.

Compatibility and Caliber Support

This large module works with P320 firing control units chambered in 9mm, .40 S&W, and .357 SIG. It accommodates both 3.9-inch carry-length slides and 4.7-inch full-size slides. One important note: if you're swapping from an older P320, make sure your magazines have the newer SIG mark baseplates rather than the older SIG SAUER branding, as the XSeries modules require that newer style. Installation is straightforward—there's no gunsmithing involved, just drop the FCU in and secure the takedown lever.

What Makes This Large Size

Choosing between grip sizes comes down to hand fit and capacity. The large size gives you the most circumference and will feel closest to a full-size duty pistol in your hand. It pairs exclusively with 17-round magazines, so if you're coming from a compact P320 with smaller grip sizes, you'll need to grab compatible magazines. The module itself weighs about 3.8 ounces and is built from durable polymer, the same material Sig uses on all its XSeries frames.
