Magazine Extension for Glock 42

$19.99 to $49.99
SKU: 1072
Now you can improve the grip on your Glock 42by adding the GSPC magazine extension for the Glock 42.

Now Available in a Combo pre-installed on a factory magazine in +0, +1, and +2 configurations.

It was designed to provide a larger grip yet still maintaining a slim, concealable profile.

Add up to 2 rounds to your Glock 42 magazine!
The new Glock 42 is the smallest and lightest Glock ever released and it just might be the perfect concealed carry handgun! The only drawbacks are the low 6 shot capacity and the very short grip. This makes it difficult to get a consistent shooting grip which affects both accuracy and speed.

We have developed this magazine extension especially for the G42 to enable you to get a full grip on the gun. It replaces the factory base plate while using the same spring. You'll find it provides a much better grip.

Watch our online video to learn just how easy this is to install.

Available in black or silver and now available in 0-Shot, 1-Shot, and 2-Shot versions.
  • +0 Style Height = 0.765" (~3/4")
  • +1 Style Height = 0.765" (~3/4")
  • +2 Style Height = 1.125" (~1 1/8")

Great improvement!


I recently purchased 2 of these, a nice addition to these magazines. I now, really like how this gun feels in my hand! Easy to install and best of all, no malfunctions.

As adevertised. And shiny.


I expected the black to match the standard grip but it's more of a shiny black metallic. This will match their other upgrades. The allen key includded in the box seemed to make marks on the side of it during shipping. But that's not y'alls fault.
