The Sig Sauer P320 Carry Grip Module in small size is the chassis foundation for building or converting a compact P320 or P250 pistol. If you already own a P320/P250 firing control unit and want to downsize to a carry-friendly platform, this grip module lets you reconfigure your modular Sig into a more concealable setup without buying a whole new gun. It's available in black and accommodates 9mm Luger, .40 S&W, or .357 Sig calibers—so long as you pair it with the corresponding slide and barrel assembly.
Modular design is one of the P320's defining strengths, and this small grip module exemplifies that flexibility. Shooters who prefer a tighter, more controllable grip-to-hand fit will appreciate the compact dimensions. It works seamlessly with your existing FCU (fire control unit), which houses the trigger, sear, and firing pin—the serialized part of the pistol. That means you're simply swapping the chassis and caliber capability, not starting over.
Whether you're building a dedicated carry gun from parts or converting an existing P320/P250 to a more packable size, this grip module delivers the modular versatility Sig engineered into the platform. The small size is ideal for shooters with smaller hands or those who prioritize concealability without sacrificing the reliability Sig Sauer is known for.

Yes. This grip module is designed to accept your existing P320 or P250 FCU (firing control unit). You simply remove your FCU from your current grip and install it into this small module to complete the conversion.
You'll need a P320 or P250 slide and barrel chambered in 9mm Luger, .40 S&W, or .357 Sig to pair with this grip module. The slide and barrel must match the caliber you intend to shoot.
The small grip size is designed for compact carry and shooters who prefer a tighter grip fit. If you have larger hands, you may find it less comfortable; consider whether a medium or large grip module would better suit your hand size.
No. The FCU is the serialized part of the P320/P250 and is the only component that must be registered. This grip module assembly allows you to reuse your existing FCU, so you're only purchasing the grip chassis and converting your current gun's caliber or size.
