Pearce Grip Pghcgx+ Extension Black Matte Polymer Fits Hellcat/Gx4 Pro Xl

The Pearce Grip Pghcgx+ Extension is a magazine base plate replacement designed to improve grip comfort and capacity on popular compact pistols. Built from black matte polymer, this extension fits the Springfield Armory Hellcat, Hellcat Pro, and Taurus GX4 and GX4 XL, making it a go-to accessory for shooters who want better control on guns they already carry and trust. The extended gripping surface and textured finish match your frame, creating a seamless, purpose-built feel that works as hard as you do.

What sets this extension apart is the patented PearceLock attachment mechanism (US 10996010 B2), which locks the extension securely to your magazine base plate without tools or fuss. Whether you're at the range, in the field, or training for defensive readiness, a solid grip matters—and Pearce Grip engineered this extension to add approximately 3/4 inch of additional gripping surface where your pinky finger needs it most.

Magazine capacity gains vary depending on your magazine and pistol model. On most Hellcat and GX4 standard magazines, you'll add one round of capacity. On Hellcat 13-round magazines, you'll maintain the round count but gain ergonomic advantage. The extension does not work with factory 10-round magazines or Hellcat Pro magazines with extended plastic spacers, so verify your mag type before ordering. For those running 10-round Hellcat magazines on the standard frame, Pearce offers the separate PG-HCGX model.

If you shoot a Hellcat or GX4 and want a no-fuss way to improve grip without a factory pinky extension, this polymer extension delivers solid value and proven reliability.

Frequently Asked Questions

Will this extension work on my Hellcat 10-round magazine?

No. This extension (PG-HCGX+) does not fit factory Hellcat 10-round magazines or Hellcat Pro magazines with extended plastic spacers. For standard-frame Hellcat 10-round mags, you need the Pearce Grip PG-HCGX model instead.

Does this extension fit my GX4?

Yes. The Pghcgx+ extension fits both the Taurus GX4 and GX4 XL.

How much grip length does this add?

The extension adds approximately 3/4 inch of additional gripping surface, plus matches the texture of your frame for a cohesive look and feel.

Will I gain a round of capacity?

On standard Hellcat and GX4 magazines, the extension adds one round of capacity. On Hellcat 13-round magazines (which come with a factory +2 extension), you'll maintain the same round count but gain improved ergonomics and grip comfort.
