Will extension work with Glock 48 Expert Answer

No, this Rival Arms Plus 2 Magazine Extension is only compatible with the Glock 43. I would recommend the Tyrant Designs Glock 43x/48, 9mm, 4-Round Magazine Extension, found by using the link below:

my favorite +2 by Jacob, Verified Owner, January 5, 2023
I have quite a few +2 extensions for my Glock 43 and this one is my favorite. Very easy installation, looks good, and feels nice. I would recommend this to anybody looking for addition mag capacity or if you’re just looking for a better grip.
