Description
The Pachmayr 03894 Grip Extender replaces your magazine baseplate to add a little extra real estate at the bottom of the grip. That means your pinky finally has somewhere to land instead of curling under the frame, and you get a fuller, more planted hold that translates to better recoil control and faster follow-up shots. Pachmayr shaped and textured these to blend right into the pistol, so once they're on they read as part of the gun rather than an aftermarket add-on.
What the Pachmayr Grip Extender Fits
This particular model covers a wide chunk of the mid and full-size Glock lineup, including the 17, 18, 19, 22, 23, 24, 25, 31, 32, 34, 35, and 37. It's worth noting these do not add magazine capacity. They're purely about grip length and comfort, not turning a compact into a higher-round setup. If you're chasing extra rounds, that's a different Pachmayr part number.
Installing the 03894 on Your Glock
Swapping these on is a quick job at the kitchen table. You pop off the factory baseplate, slide the extender down onto the magazine body, and lock it back into place over the internal floorplate. Most folks knock it out in a couple of minutes with a punch or a baseplate tool. A short how-to video is handy the first time if you've never pulled a Glock mag apart, but after one you'll have the routine down.
Built to Take a Beating
Pachmayr molds these from tough, high-strength polymer that shrugs off drops, dust, and daily carry wear. The two-pack is a nice touch since most of us run more than one magazine, so you can outfit a spare and keep a consistent feel across your rotation. Black finish keeps things low-key and matches the standard Glock aesthetic.

Frequently Asked Questions
Does the Pachmayr 03894 grip extender add magazine capacity?
No, this model is strictly about grip length and comfort, not extra rounds. It replaces the baseplate to give you a fuller grip surface without changing how many rounds the magazine holds. If added capacity is your goal, Pachmayr makes separate part numbers that convert certain Glock mags to higher counts.
Which Glocks does this grip extender fit?
It's designed for mid and full-size Glock magazines, covering the 17, 18, 19, 22, 23, 24, 25, 31, 32, 34, 35, and 37. It is not intended for the subcompact frames like the 26 or 27, which use a different Pachmayr collar. Always match the magazine body, since these install onto the mag rather than the frame.
How hard is it to install the Pachmayr grip extender?
It's a straightforward swap that most people finish in a couple of minutes per magazine. You remove the factory baseplate, slide the extender onto the magazine body, and lock it back over the internal floorplate. A baseplate tool makes it easier, and a quick how-to video helps if it's your first time taking a Glock mag apart.
How many extenders come in the pack?
You get two per pack, which is handy since most people carry more than one magazine. That lets you set up a spare so the grip feel stays consistent across your rotation.
