Pearce Grip PG2733 Polymer Magazine Extension for Glock 26/27/33/39 - Adds Capacity, Enhanced Grip - Black Finish

The Pearce Grip PG2733 polymer magazine extension is a practical upgrade for compact Glock shooters who want better control and grip without sacrificing concealability. Whether you carry a Glock 26, 27, 33, or 39, this extension replaces your magazine base plate and internal floor plate to add extra length and a more comfortable grip purchase—critical for smaller-frame pistols where finger positioning matters in a defensive or range scenario.

Built from high-impact polymer, the PG2733 is engineered to match your Glock's factory appearance and texture. It's tough enough to handle drops across a wide temperature range (–20°F to 350°F), so it won't let you down in harsh conditions or hard use. The extension adds approximately 5/8" to your magazine length, giving your pinky and ring finger a more natural resting point without adding bulk that ruins everyday carry.

Magazine capacity varies by model: the extension adds two rounds to a Glock 26 mag, one round to 27 and 33 configurations, and zero to the 39. If you're running 4th generation Glock models, Pearce Grip recommends the PG-G42733 variant. The extension also features Mag-Track identification, a simple but useful way to keep tabs on your magazines if you rotate them between pistols.

Frequently Asked Questions

Will this extension fit my Glock 27 or 33?

How much magazine capacity does it add?

Capacity gain depends on your model. A Glock 26 magazine gains two rounds; a 27 or 33 gains one round. The Glock 39 extension does not increase capacity but still improves grip length and comfort.

Does the extension ruin concealability?

No. The extension adds only about 5/8" of length, positioning it as a middle ground between compact mags and full-size alternatives—you gain better finger room and grip control without the bulk that makes everyday carry impractical.

What's included and how does installation work?

The PG2733 includes the polymer extension itself. Installation involves removing your magazine's original base plate and internal floor plate, then installing the extension in their place. Refer to Pearce Grip instructions or your Glock manual for detailed steps.
