The ProMag Grip Spacer Adapter for Glock 19/23 Magazines to Fit 26/27 is a straightforward, practical solution for compact Glock shooters who want more magazine capacity without swapping frames. If you carry a Glock 26 or 27—respected for their size and portability—but want the extra rounds that a full-size Glock 19 or 23 magazine provides, this polymer adapter bridges that gap. It lets you run longer magazines in your subcompact while keeping your gun's concealable profile intact.
The spacer works by filling the gap between your 26/27 frame and the floor plate of the longer 19/23 magazine, creating a proper fit and grip extension. A single Allen head cap screw secures it in place—no gunsmith visit needed. The textured polymer surface matches the finish of your Glock frame, so it looks like it belongs there rather than bolted on as an afterthought. Made from durable injection-molded black polymer, it's built to handle regular carry and shooting use.
This is one of those accessories that makes sense if you've already invested in Glock's ecosystem and want to maximize versatility. Your 19/23 magazines stay in your safe or range bag; on your 26 or 27, you get more capacity when you need it. Installation takes minutes, and the design is clean enough that it doesn't compromise your gun's ergonomics or concealability.

No. The spacer is held in place by a single Allen head cap screw and can be installed or removed in minutes without professional help.
What magazines does this adapter allow me to use?
This spacer lets Glock 19 and Glock 23 magazines function properly in your Glock 26 or 27 frame. It fills the gap between your subcompact frame and the longer magazine's floor plate.
