Glock 17 + 5 Mag Extension

Published by Daniel on Oct 22nd 2025

Solid piece of kit — cleans up the Glock 17 grip, adds capacity and doesn’t get in the way of reloads. Installation was drop-in simple, the finish matches my factory baseplate well, and the extension feels rock-solid on the mag (no wiggle or loose play). Ergonomically it gives a bit more purchase for larger hands without making the grip bulky or snaggy. If you need a reliable, low-profile way to get a few extra rounds and better grip purchase on a Glock 17, this extension is an easy recommend.

Was a little skeptical of the design at first but figured I’d give them a shoot. So far they are holding up great. Dropped them on concrete multiple times and zero issues. Installation was extremely easy and actually was a true plus 5.

This product is perfectly constructed. It fits well with the mag. Good paint.

Plus 5 Mag extensions

Published by Quentin McKnight on Jun 5th 2025

I have seven of the +5 ext’s, so that should say a lot. The finish is nice and the durability is there. I like these a lot and carry one in my EDC setup.

Best extension on the market

Published by Breland Brooks on Jan 25th 2025

The ergonomics and esthetics without compromising reliability put this at the top of the game. Makes for easier draw with the extension and it looks cool and that's what it's about.

Mag extensions

Published by Love em on Jan 24th 2025

Super solid construction, put one on and beat the shit out of it. Threw it at the ground and beat it up, no issues and didn’t even scratch that badly. Got two but now I want a few more, only wish they came in more colors without having to pay extra but I do like the black and spray paint is cheap.

+5

Published by Preston on Jul 22nd 2022

Bought this for my gen 5 17 as it is running a Jagerwerks milled slide and I wanted to finish it off with this extension. I replaced the OEM glock +2 with this one, which is a pretty similar install. To my surprise this +5 is just barely bigger than the OEM +2. I will be purchasing a few more soon!
