The Sig Sauer P320 Grip Module X-Series Compact in small size puts customization at your fingertips. If you own a P320 or P250 with a firing control unit, this grip module lets you reconfigure your pistol into a compact 9mm Luger, .40 S&W, or .357 Sig without buying an entirely new gun. Swap in your existing FCU, pair it with a compact or sub-compact slide and barrel assembly, and you've got a fresh platform tuned to your preferences—all without the expense of a full firearm purchase.
Built from durable black polymer, the X-Series Grip Module X-Series Compact is engineered for the modular P320 ecosystem. The small size module fits Sig P320 compact frames with 3.60" and 3.90" barrels, giving shooters who prefer a narrower grip or carry a tighter, more manageable feel. This is the grip module that serious P320 owners use to expand their platform's versatility—whether you're building a range gun, carry setup, or dedicated hunting rig in multiple calibers.
One important note: the X-Series grip module requires a compact or sub-compact slide assembly and is not compatible with full-size P320 frames (it will leave the recoil spring and guide rod exposed on full-size dust covers). Magazine compatibility matters too—the X-Series module works with magazines bearing the SIG Mark baseplate; older magazines printed with "SIG SAUER" text on the baseplate are not compatible. Confirm your slide length and magazine baseplates before ordering to ensure a seamless build.
