Hogue 18220 Extension Base Pad Fits Glock 42 Compatible w/ 6rd Magazine Black Overmolded Rubber
The Hogue 18220 extension base pad for Glock 42 magazines transforms how your compact .380 ACP pistol feels in hand. This 6-round magazine extension wraps below the mag body with overmolded rubber, adding a full finger groove that makes a significant difference in grip control and reload speed—especially important when you're running a slim single-stack carry gun. If your pinky finger normally slides off a Glock 42 mag during shooting or reloads, this pad solves that problem without forcing you into a gun change or a compromise grip.
Built from durable thermoplastic elastomer, the extension is textured with Hogue's signature Cobblestone pattern for traction that stays put whether your hands are dry or you're transitioning between positions. The pad also absorbs some impact if you drop the magazine during a reload—a practical benefit that extends your magazine's service life. Installation is straightforward and requires no tools or permanent modification to the magazine itself.
This is a straightforward ergonomic upgrade for Glock 42 shooters who want better handling and comfort without added bulk or weight. It works exclusively with 6-round magazines for the Glock 42 .380 ACP, so verify your mag capacity before ordering. The magazine itself is not included.
