I posted this in another forum and I thought I would pass this along. My latest box of goodies came from Midway yesterday, an in it was a .45 mag carrier for the 7-round XDS mag that accompanied it.
To my surprise, the mag carrier also worked for the 9mm shield mags - the shied mag was a bit snug, but still easy to extract. So I ordered another one for my Shield (I would not use one for both the .45 and the Shield, as the Shield mag is a "stack and a half" and will likely cause the carrier to stretch so that the .45 mag may lose its snug fit.)
The carrier is here:
El Paso Saddlery Single Mag Pouch Single Stack Mag Leather Russet
It's currently out of stock but the black one is available. I thought I would pass this along, as finding a mag carrier for the shield is not easy.
