The Magpul EHG SG9 Full Size frame is a polymer replacement grip frame purpose-built for the SIG Sauer P320 platform. If you're running a full-size P320 and want better ergonomics, control, and customization options than the factory frame, this drop-in replacement delivers Magpul's 25 years of polymer expertise applied directly to pistol design. It works seamlessly with all OEM P320 trigger modules, standard 17-round magazines, and existing small parts—no gunsmith work required.

The grip itself prioritizes shootability and confidence. A ¾-scale TSP (textured surface pattern) covers the frame for a secure hold even when hands are wet or cold. The magazine well features an integral flare designed for quick, intuitive reloads—Magpul calls it "carry-sized," meaning it doesn't extend far beyond magazine dimensions, keeping the gun handy without bulk. A 1913 Picatinny rail runs underneath, ready for Surefire, Streamlight, or compatible weapon lights. For shooters who carry with a lanyard, a slot is molded into the backstrap. The frame measures roughly 1.25 inches wide and weighs just over 4 ounces.

One standout is the Magpul Magazine Release pre-installed on the frame. It's steel with a QPQ finish to fight corrosion, contoured for positive finger engagement, and fully reversible—set it up right-handed or left-handed in seconds. This is the kind of attention to detail that separates a useful upgrade from a true improvement. Made in the USA, this frame is available in black and fits all SIG P320 full-size models that accept 17-round magazines (excludes manual-safety variants). Known to work with major holster lines including Safariland, Blade-Tech, Raven Concealment, Blackhawk, and Fobus.
