The Hogue 18033 OverMolded Extension Base Pad is a grip-enhancing magazine accessory purpose-built for Sig Sauer P365 and P365-380 owners running 12-round magazines with a HandALL Beavertail Grip Sleeve. If you shoot a P365 and want a full, secure grip on your reload—especially when speed matters—this extension base pad solves a real problem: it gives your pinky finger a proper purchase point instead of riding air, and it protects your magazine during those ground-contact reloads that happen in training and matches.
The pad is molded from a thermoplastic elastomer that holds up to years of use without degrading or becoming tacky. Hogue's signature Cobblestone texture runs across the surface, which works double duty—it improves comfort on reload drills and provides reliable grip even if your hands are wet or gloved. The Flat Dark Earth color matches modern P365 aesthetics and blends with most carry setups.
Installation is straightforward: a single screw fastens the pad to your existing 12-round magazine. Just note that this pad is engineered specifically for Sig 12-round magazines paired with the HandALL Beavertail Grip Sleeve—compatibility is precise, and it won't fit other magazine types or grip configurations. The magazine itself is not included.

Frequently Asked Questions
Will this extension base pad work with my Sig P365 magazine without the HandALL Beavertail Grip Sleeve?
No. This pad is designed specifically for use with the HandALL Beavertail Grip Sleeve and is compatible only with Sig 12-round magazines in that configuration. Compatibility is precise, and it won't fit other setups.
Does the pad come with a magazine?
No. The extension base pad is sold separately. You'll need a Sig Sauer P365 12-round magazine to attach it to.
How difficult is installation?
Installation is simple—a single screw fastens the pad to your magazine. No gunsmithing or special tools are required.
Will this pad protect my magazine if I drop it during training?
Yes. One of the key benefits of the extension is that it shields the magazine body during ground contact and quick reloads, reducing impact damage to the magazine itself.
