XGRIP for SIG Pistols | P320 Mag Adapters
XGRIP for SIG SAUER Pistols — Magazine Adapters & Grip Extensions
The XGRIP® for SIG SAUER gives you the best of both worlds: the capacity of a full-size magazine with the comfort and concealability of a compact or subcompact pistol. Whether you carry daily or train regularly, these adapters transform how your SIG feels in hand, offering better control, more rounds, and a flawless OEM fit that looks like it came straight from the factory.
Made in the USA from durable polymer, every XGRIP is precision-engineered to fit your SIG SAUER perfectly — extending your grip without compromising reliability or performance.
Why Choose XGRIP for Your SIG SAUER
If you shoot a SIG P320 or P250, you already know how balanced and accurate these pistols are. But shorter grips on compact and subcompact models can limit control and capacity. The XGRIP adapter changes that instantly.
It allows you to use full-size or compact magazines in your smaller-frame SIG, providing a more natural, comfortable hold and improved handling under recoil.
Key Benefits:
-
Better Control: Extends your grip for greater stability and faster follow-up shots.
-
Increased Capacity: Run full-size or compact mags in smaller pistols for more rounds per reload.
-
Seamless Fit: Designed to match your pistol’s frame with no gaps or wobble.
-
Fast Installation: Slides over your magazine — no tools or gunsmithing required.
-
Proven Reliability: Trusted by law enforcement, military, and competitive shooters worldwide.
The XGRIP enhances your SIG’s ergonomics and versatility, turning one pistol into multiple configurations for carry, training, and duty.
