The Hogue 18040 OverMolded Extension Base Pad is purpose-built for shooters running a Sig Sauer P365 or P365-380 equipped with Hogue's HandALL Beavertail Grip Sleeve. This extension pad mounts to the bottom of Sig's 15-round magazines, giving you that extra finger groove that makes a real difference when you need a secure, full-hand grip—especially during tactical transitions or rapid reloads. If you're carrying a compact 9mm and want the ergonomic confidence of a three-finger hold without adding bulk to your gun, this is the straightforward solution.
Built from durable thermoplastic elastomer that won't degrade over years of training and carry, the Hogue pad features the brand's signature Cobblestone texture pattern for authentic grip feel without slipping in your hand. The textured surface also provides a measure of protection to your magazine during those inevitable ground drops on the range or in the field. Installation is simple—a single screw is all it takes. Note that this pad is engineered specifically for Hogue's HandALL Beavertail Grip Sleeve and Sig's 15-round magazines; compatibility is tight by design.
Whether you're fine-tuning your EDC setup or maximizing control on your competition P365, this extension delivers measurable grip improvement where it matters most: in your hand. It's the kind of modest upgrade that pays off every time you draw.
