Hogue 18043 OverMolded Extension Base Pad Cobblestone Fits Sig Sauer P365 15rd FDE Rubber
$16.11
The Hogue 18043 OverMolded Extension Base Pad adds real comfort and control to your Sig Sauer P365 or P365-380 equipped with the HandALL Beavertail Grip Sleeve. If you've felt your pinky finger cramped or hanging off the back of the magazine during extended shooting sessions, this extension base pad is a straightforward fix that makes a noticeable difference in how the gun feels in your hand.
Built from durable thermoplastic elastomer with Hogue's distinctive Cobblestone texture, the extension provides an extra finger groove below the magazine while maintaining the Flat Dark Earth finish of your P365. It's not just ergonomic—the rubber pad also protects your magazine from damage during quick-reload ground drops at the range or in the field. Installation takes just a single screw, and the pad is made to last through years of hard use without degrading.
This accessory works exclusively with SIG 15-round magazines and the HandALL Beavertail Grip Sleeve, so confirm compatibility with your current setup before ordering. Whether you're running drills at the range or carrying daily, a full grip contributes to faster, more accurate shooting.

Frequently Asked Questions
Will this base pad fit my Sig P365 magazine?
Yes, the Hogue 18043 is designed for SIG 15-round magazines paired with the HandALL Beavertail Grip Sleeve on the P365 or P365-380. It will not fit other magazine types or guns.
Do I need the HandALL Beavertail Grip Sleeve for this to work?
Yes, this extension base pad is compatible only with the HandALL Beavertail Grip Sleeve, so you'll need both to achieve the proper fit and ergonomics.
What's included in the package?
The extension base pad is included; the magazine, grip sleeve, and installation hardware are not, so confirm you have a compatible SIG 15-round magazine and the HandALL Beavertail Grip Sleeve before installing.
How is this different from just a standard magazine base?
The extension lengthens the magazine base to give your pinky finger a proper grip surface rather than hanging off the back. The Cobblestone texture and rubber construction also protect the magazine during fast reloads and drops on hard surfaces.
