Glock 43X/48 – S15 / S10 Magazine Extension – +2 Capacity – Black
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The Shield Arms S15 / S10 +2 Magazine Extension is a billet aluminum extension for the Shield Arms S15 and S10 magazine ecosystem built around Glock 43X and Glock 48 platforms. It adds two rounds to the compatible magazine while keeping the setup cleaner and more compact than the bigger +5 extension route.
Fitment
- Fits Shield Arms S15 Gen 2 and Gen 3 magazines for Glock 43X / Glock 48
- Also tied into the Shield Arms S10 chopped-frame magazine ecosystem per Shield Arms product family support
- Adds +2 rounds
Does NOT fit
- Not for OEM Glock polymer magazines
- Not a universal Glock magazine extension
- Not for double-stack Glock magazine bodies outside the S15/S10 family
What it does
This extension bumps capacity while keeping overall length more manageable than a +5 setup. It is a good fit for shooters who want more rounds without hanging a long extension off the bottom of the mag.
Why it’s worth it
Not everybody wants to turn a slimline Glock mag into a boat anchor. The +2 setup is a cleaner middle ground for carry-minded or lower-profile use.

Verify whether you are running an S15 or S10 family magazine and confirm your exact Glock 43X / 48 setup before purchase. This is not for OEM Glock mags.
