Description
This is the genuine factory grip module from SIG SAUER for their modular P320 and P250 platforms. If you've ever felt your pistol needed a better fit to your hand, this is the simplest fix you'll find. Drop your fire control unit into this large carry-sized frame and you've customized your gun's feel and function without touching the serialized parts.
What Makes the Carry Size Special
The carry configuration gives you a full-length grip paired with a compact slide, striking a balance that appeals to folks who want a solid hand hold but a more manageable overall package. It accepts the same 17-round magazines as full-size P320s while keeping your gun's footprint reasonable for daily carry. This is why law enforcement agencies have gravitated toward the carry size for duty weapons.
Caliber and Compatibility
This module works with 9mm, .40 S&W, and .357 SIG chamberings across both P320 and P250 platforms. Just remember you'll need the corresponding slide and barrel assembly to complete the setup. The large grip size works best for shooters with bigger hands or those who prefer a roomier grip circumference. SIG offers this in small and medium options too if you need to dial in the fit.
Installation and Build Quality
Swapping modules takes minutes and requires no tools or gunsmithing. The polymer construction is durable enough for daily use while remaining lightweight. The factory texture grips well even when things get wet, and it's built to SIG's standard specifications for that direct factory fit. Grab your fire control unit from your current P320 or P250, press it into place, and you're ready to test out how different this frame feels in your hands.

Frequently Asked Questions
What exactly do I need to get this grip module working?
You'll need your P320 or P250 fire control unit (the trigger group), plus the correct slide and barrel assembly for your caliber. The grip module is the lower frame that houses your FCU. Just drop your existing trigger group into this frame and you're set.
Will the carry-size grip module work with my compact slide?
No. The slide length needs to match the frame type. Carry-size modules pair with carry-size slides. If you're trying to build a different configuration, you'll need to match up your slide, barrel, and grip module correctly or check compatibility charts to avoid fitment issues.
How hard is it to swap this grip module onto my P320?
Very simple. Field strip your pistol, remove your fire control unit from the old grip, and press it into the new one. The whole job takes a few minutes and needs no special tools. SIG designed the P320 specifically to make this modular swap quick and easy.
Do I need any special paperwork or licenses to buy this grip module?
No. Grip modules are not serialized and are treated as parts, not firearms. You can order it and have it shipped directly to your door without any FFL paperwork or restrictions.
