The Hogue 18020 OverMolded Extension Base Pad is a purpose-built magazine accessory designed to improve grip and control on your Sig Sauer P365 10-round magazines. If you carry a compact 9mm and find yourself reaching for a better purchase on reloads or want more finger real estate during rapid fire, this extension base pad solves both problems—adding a full finger groove below the magazine while you're holding it.
Built from durable thermoplastic elastomer, the base pad won't crack or harden over years of range trips and carry. The Cobblestone texture is Hogue's signature aggressive pattern, engineered to provide bite without tearing up your hands or gear. Installation is straightforward: a single screw secures it to your existing 10-round Sig magazine (works with the HandALL Beavertail Grip Sleeve). The extension also protects your magazine from impact damage during tactical reloads or training scenarios where mags hit the deck.
This is the kind of small upgrade that pays dividends in dry fire practice and on the range—better ergonomics mean faster, more controlled shooting. It's also popular with carry shooters who want maximum grip leverage in a defensive situation without changing their gun or holster setup.
