Sig Sauer Grip Module Assembly Sig P320, P250 9mm Luger, 357 Sig, 40 S&W

The Sig Sauer Grip Module Assembly is a core upgrade for P320 and P250 shooters who want to customize fit and ergonomics without buying a new gun. This small, compact-length grip module accepts your existing Sig fire control unit (FCU) and works with 9mm Luger, .357 Sig, and .40 S&W slide and barrel assemblies. If your hands run smaller or you prefer a snappier, more concealable carry profile, swapping in a properly-sized grip module transforms how your pistol feels in your hand—and it takes minutes, not a gunsmith visit.

Sig's modular platform is built on the idea that your gun should fit you, not the other way around. The P320 and P250 grip modules come in three girth sizes (small, medium, large) and different slide lengths (compact/carry and full size), so you can dial in exactly the combination that works for your hands and your mission. This particular module—small size, compact length—is ideal for shooters with smaller hands, those building a carry gun, or anyone who values a trimmer profile at the range or in the field.

The grip module arrives finished in black, ready to drop into your setup. As long as you have a compatible FCU and the right slide and barrel for your caliber, you're good to go. It's a straightforward, proven way to make a P320 or P250 feel like it was built for you.
