Hogue 18050 OverMolded Extension Base Pad Cobblestone Fits Sig Sauer P365X/XL 15rd Black Rubber
The Hogue 18050 OverMolded Extension Base Pad is a purpose-built magazine extension for the Sig Sauer P365X and P365XL that gives you what these compact carry guns need: room for your pinky. Built from durable OverMolded rubber with Hogue's trademark Cobblestone texture, this pad extends your 15-round magazine just enough to fill out your grip, making fast reloads more controlled and your shooting hand more stable. It's the kind of small upgrade that makes a real difference in how a subcompact handles during training or when it counts.
Hogue engineered this extension to work specifically with the P365X/XL and the HandALL Beavertail Grip Sleeve (when used together). The Cobblestone texture isn't just for looks—it delivers the tactile grip security you want on a defensive carry gun, even when you're moving fast or your hands are less than dry. The thermoplastic elastomer material ages gracefully, resisting UV degradation and the sweat and wear that break down lesser rubber over time.
Installation is straightforward: a single screw holds the pad in place on your 15-round magazine. Beyond comfort, the extension also shields your magazine from damage during dynamic training or those inevitable moments when a mag hits the ground during a reload. If you shoot your P365X/XL regularly, this is a practical addition that costs far less than replacing a damaged magazine.
