Sig Sauer 9/40/357 Full Size Large Grip Module, Black
The Sig Sauer 9/40/357 Full Size Large Grip Module is a genuine polymer grip designed to customize your P250 or P320 platform pistol. If you're running a modular Sig and want a larger grip profile for better control and comfort, this genuine factory grip delivers the ergonomics and durability Sig is known for. The black finish matches standard Sig aesthetic and the textured polymer surface keeps your grip secure even when things get wet or your hands are sweaty—essential when you're serious about shooting.
This is a grip module swap, not a complete pistol. You'll need a firing control unit and compatible slide and barrel assembly (9mm, .357 SIG, or .40 ACP) to complete a functional gun. If you already own a P250 or P320 and are looking to upsize or refresh your grip, this module is straightforward to install with basic familiarity and the right tools.
Sig's modular design is built on the idea that your gun should fit your hand, not the other way around. Whether you've outgrown a smaller grip or you're building a custom configuration, the Full Size Large option gives you more real estate for a proper purchase and control. Genuine Sig parts maintain reliability and fit standards across the entire P250/P320 ecosystem.
