Mag Catch Requirement
It is required to swap out your plastic OEM mag catch with either Shield Arms' standard steel mag catch or their premium steel mag catch. Here's why. If you don't swap your mag catch you may have reliability issues. If you use another manufacturer's mag catch you may have reliability issues. Gen 2 and 3 magazines were designed to work with Shield Arms steel mag catches. If you have a first generation aluminum mag catch, it is required to upgrade to one of our steel mag catch offerings.

Magazine Restriction
Please check with your state regulations for ownership of large capacity magazines.

They work like a champ
Good product to expand round capacity on the 43X. I normally change all my mag releases to metal anyway, so was a good deal it was included with the mags. Just put ~150 rounds through them with zero malfunctions. Great value from Brownell’s and very fast shipping, which is always appreciated. Highly recommended!

Shield Arms Mags
Installed the steel mag release, and all four mags ran as they should. The mags release as they should without having to grab them or do the “wrist flick”
