FAQ
Will this increase my magazine capacity?
No. The J-Plate is a direct replacement for the factory base pad and does not alter the internal magazine length or follower travel. Capacity remains factory-spec.
Does it fit OEM Glock® magazines?
No. This pad is designed specifically for Magpul® GL9 PMAG™ magazines only. It will not fit standard Glock® factory magazines.
Do I need to buy additional parts to install this?
No. The J-Plate uses the factory retention plate already installed on your Magpul® magazine. No springs, followers, or extra hardware are required.
