Pearce Grip Extensions Glock 29/20/21 Plus Two – PG-1045

Pearce Grip Extensions Glock 29, 20, and 21 Plus Two, part number PG-1045, add real estate to the bottom of your magazine and two additional rounds to your capacity. Large-frame Glocks have plenty of grip for most hands, but the pinky still tends to hang off the bottom.

Grip extensions are one of the cheapest meaningful upgrades available for a handgun. They change how the pistol feels in the hand, and feel drives control.

What Pearce Grip Extensions Glock owners get

Pearce Grip Extensions Glock owners buy in the Plus Two configuration are floorplate extensions designed for the Glock 29, Glock 20, and Glock 21 magazine family. They replace the factory floorplate and lengthen the magazine body enough to accommodate two additional rounds.

The immediate benefit for most shooters is the full firing grip. Getting all four fingers on the pistol rather than three plus a floating pinky improves recoil control significantly, especially on the 10mm and .45 ACP chamberings these frames carry.

Competition shooters, range shooters, hunters carrying a 10mm in the backcountry, and anyone with larger hands will appreciate the change. The additional capacity is a bonus on top of the ergonomic improvement.

Specifications, fit, and function

The Plus Two designation is the specification to note. Extensions come in various capacities, and this one is a two-round increase rather than a one-round or three-round version, which keeps the magazine long enough to be useful without becoming unwieldy.

Fitment covers the Glock 29, 20, and 21, which share a magazine family across 10mm and .45 ACP. Verify your specific magazine before ordering, since Glock magazines vary by generation and by frame size in ways that are easy to overlook.

Adding length to a magazine has consequences for the spring. Any extension requires the spring to travel further, so pay attention to feeding reliability during your first few range sessions and replace tired springs before blaming the extension.

The contoured profile is what makes the finished pistol look intentional. An extension that follows the frame lines reads as part of the gun, while a squared-off block advertises itself from across the room.

Installation, care, and compatibility

Installing Pearce Grip Extensions on Glock magazines is a five minute job. Unload the magazine completely, depress the retention plate, slide the factory floorplate off while controlling the spring, and reassemble with the extension in place.

Control the spring during disassembly. Magazine springs are under real tension and they will launch the follower and plate across the room if you let go, so work over a table and keep a hand on top of the assembly.

Function check every modified magazine with live fire before trusting it. Load to full capacity, confirm the rounds feed cleanly, and verify the slide locks back on empty. Do this for each magazine individually rather than assuming they all behave the same.

Keep the extension and magazine interior clean and dry. Extensions add length where lint and grit accumulate, so break the magazine down occasionally, wipe the follower and spring, and reassemble without oil.
