Hogue 18030 OverMolded Extension Base Pad Cobblestone Fits Sig Sauer P365 12rd Black Rubber
$16.11
The Hogue 18030 OverMolded Extension Base Pad is a purpose-built magazine extension for the Sig Sauer P365 and P365-380 that solves a real problem for compact carry shooters: giving your pinky finger a proper perch. If you run the factory 12-round magazine on your P365, this extension fills the gap below the baseplate and creates an extra finger groove, transforming your grip from cramped to controlled. It's the kind of small refinement that makes a noticeable difference when you need a solid purchase on a tiny carry gun.
Built from Hogue's proven OverMolded rubber compound—a thermoplastic elastomer that won't harden or degrade over time—the pad is textured with their signature Cobblestone pattern. That knurling isn't just for looks; it meaningfully improves purchase in wet conditions or when you're moving fast. The extension also shields your magazine during ground contact and quick reloads, protecting the critical feeding lips and spring from impact damage. Installation is straightforward: one screw holds it in place, no gunsmithing required.
Important note: this extension is engineered specifically for Sig's factory 12-round magazines and pairs with Hogue's HandALL Beavertail Grip Sleeve for the P365. If you're running the short factory grip or a different grip system, verify compatibility before purchasing. The magazine itself is not included—you'll need a Sig P365 12-round mag to use this pad.

Frequently Asked Questions
Will this work with my Sig P365 magazine?
Yes, but only with Sig factory 12-round magazines. The extension is designed specifically for that capacity. If you're using aftermarket magazines or different capacity mags, compatibility is not guaranteed.
Does this fit the short grip P365, or do I need a specific grip?
This extension is engineered to work with Hogue's HandALL Beavertail Grip Sleeve for the P365. If you're running a different grip system or the bare factory grip, verify fitment before purchasing.
What comes in the box?
You receive the OverMolded extension base pad and the mounting screw. The magazine is sold separately—you'll need a Sig P365 12-round magazine to attach the pad to.
How durable is the rubber material?
Hogue's OverMolded thermoplastic elastomer is engineered to resist hardening, cracking, and UV degradation over years of regular use. The material ages gracefully and maintains its texture and grip properties in varying conditions.
