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!

by

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.

Glock 42 +2 Mag Extension

by

I recently just purchased 2 of these and they came today. Instal was quick. Took prolly 5 min to do both extension. (I had the Glock Mag Tool from Glock Store)

Man what a difference these make on my Glock 42. With original Glock Mags I couldn't get a full grip. Installing the +2 mag extension in black has now given me a full grip. The gun feels sooooo much more comfortable in the hands. Much better control of the gun as well and they look great.
Great product and would recommend to anyone looking for a more real-estate on your pistol .
grip. Bonus of 8 rounds now over the stock 6 rounds.

Great product.

Great product. However the video that shows you how to install the extension should be revised. After cutting the tabs off. Put the extension plate on a table, then drop the plastic piece in so the button is in the hole. Depress the mag spring and start sliding the mag onto the base plate. It will pop right into place. I tried several times the way the video says, but the insert plate would slip down into the magazine and it was almost impossible to get it apart. I had parts flying all over the place. Then I did it my way. Fast, simple, no parts flying, and no trouble with the insert plate.

Best available necessity for G42

by

Been looking and these mag extensions are the best out there. Bigger, beefier and let you get a full hand on a G42 grip. The weapon is next to useless without one of these.
Wish they came in colors but the aluminum base with a houge grip wrap really looks just fine and feels great.

Makes a Big Improvement and Difference.

I just put the +1 of these on my G42, and I really love how the gun grips now, with my pinky on the extension. Big improvement. And it doesn't hinder my pocket carry, using a DeSantis pocket holster. This is a really good product, IMO. Thanks for it
