Description
The Magpul EHG SG9 is a replacement grip frame built for the SIG Sauer P320 Full Size, aimed at shooters who want more from their pistol’s ergonomics and controls without abandoning the P320’s modular ecosystem. It accepts OEM P320 trigger modules configured for a manual safety, so the manual safety cutout isn’t an afterthought — the frame is engineered around that safety variant from the start. All standard P320 components slot in without modification: OEM 17-round magazines, base plates, and small parts all retain full compatibility.
The grip surface uses Magpul’s 3/4-scale TSP texture, a pattern that covers the contact zones where your hand actually applies pressure while leaving smoother panels where aggressive stippling would cause discomfort during extended carry. The frame comes with a Magpul-designed steel magazine release already installed. That release is reversible for left-handed shooters, finished in QPQ for corrosion and wear resistance, and contoured with jimping so your thumb finds and actuates it positively without fumbling. The integral magazine well flare is sized in what Magpul calls a carry profile — enough of a funnel to speed up reloads under stress, but not so pronounced that it prints noticeably under a cover garment.
A full-length M1913 Picatinny rail runs under the dust cover for mounting lights or lasers, and a lanyard slot is cut into the base of the backstrap for retention setups. The entire frame is polymer construction, which keeps weight down, and is finished in Flat Dark Earth. Made in the USA.
