The Magpul EHG SG9 Compact grip module (Magpul part no. MAG1431-BLK) is a purpose-built polymer frame for the SIG Sauer P320, engineered as a drop-in replacement that gives shooters Magpul’s proven ergonomics on a proven pistol platform. This compact-size module is a stripped frame, meaning it accepts your existing OEM P320 fire control unit and internals rather than shipping as a complete pistol. It’s the upgrade path for anyone who wants a better grip angle and texture without giving up factory-tested reliability, whether for daily carry or range use.
