The Sig Sauer P320 Grip Module X-Series in medium size is a straightforward way to customize the ergonomics and appearance of your full-size P320 handgun. If your P320 feel isn't quite right in your hand or you want to refresh its look, swapping grip modules is faster and cheaper than buying a new gun. This medium-girth module fits the full-size P320 frame (4.70" slide length) and accepts fire control units chambered in 9mm Luger, .40 S&W, or .357 Sig — all you need to do is transfer your existing FCU and slide assembly into the new grip.
The X-Series design includes an extended beavertail, a feature that many shooters prefer for added hand coverage and a higher grip tang, which can improve recoil management and shot placement consistency. The black polymer construction keeps weight down while delivering the durability Sig is known for. Whether you're a competition shooter fine-tuning your setup, a carry gun enthusiast building a backup, or someone who simply wants their P320 to feel better in hand, this grip module is the fastest path to a custom fit without any gunsmithing.
Grip module swaps are one of the P320's best features—the modularity means you can experiment with sizes and styles without losing your investment in your slide, barrel, or fire control unit. If you've already got a P320 and want to dial in the ergonomics, this medium X-Series module is a no-fuss upgrade.

| Product | P320 Grip Module X-Series |
| Size | Medium |
| Frame Length | Full Size (4.70" slide) |
| Caliber Compatibility | 9mm Luger, .40 S&W, .357 Sig |
| Material | Black Polymer |
| Design Feature | Extended Beavertail (X-Series) |
This medium X-Series grip module is built for full-size P320 frames with a 4.70" slide. It will accept fire control units in 9mm Luger, .40 S&W, or .357 Sig. If you have a compact or carry-length P320, you'll need a compact grip module instead.
No special tools are required. You simply remove your current slide assembly and fire control unit from your existing grip, then drop them into the new grip module. It's a straightforward swap.
P320 grip modules come in small, medium, and large girth sizes to accommodate different hand sizes and grip preferences. Medium is a middle-ground option; if your hands are smaller, small might suit you better; if they're larger, large is available. The right fit improves control and comfort.
The extended beavertail on X-Series grips provides more hand coverage at the rear of the frame and a higher grip tang. Many shooters find this improves control during recoil and helps with consistency when shooting rapid strings.
