X-GRIP Magazine Adapter for SIG SAUER P320 & P250 Compact
The X-GRIP® for SIG SAUER P320 and P250 Compact turns your compact pistol into a full-size performer. Whether you’re carrying daily, training, or on duty, this mag adapter lets you use full-size SIG magazines in your compact frame — giving you a secure, comfortable grip and extra capacity without sacrificing control or concealment.
Built from durable polymer and engineered for a seamless fit, the X-GRIP blends the lines between compact and full-size SIG performance. You get the comfort of a full-size grip with the versatility of a compact pistol, all while maintaining factory reliability.
Why the X-GRIP Makes a Difference
Every shooter knows the challenge — balancing concealability with capacity. The P320 and P250 Compact are excellent for carry, but their shorter grip can feel limiting, especially during fast strings or extended sessions at the range. The X-GRIP adapter changes that.
With the X-GRIP installed, your compact frame gains the ergonomics, control, and magazine capacity of a full-size pistol. The result:
-
Improved Grip Control: Fills the gap between your compact frame and full-size magazine.
-
Extended Magazine Capacity: Use factory full-size mags in your compact P320 or P250.
-
Seamless Integration: Matches your pistol’s contour for a factory look and feel.
-
Enhanced Comfort: Keeps your support hand in the right position for better recoil management.
-
No Gunsmithing Required: Installs in seconds — simply slide the adapter over the magazine.
The X-GRIP provides the confidence of a full grip without changing your pistol’s profile. It’s simple, tough, and made for real-world performance.
