That does look nice as a way to conceal your Shield. Something like that would likely work for me at work. Policy is that I can't carry at work. I usually don't because however I carry, in a traditional holster, it will become exposed at some point. A pouch like that would probably hide my XDs pretty well.I was looking to see if I could find a small utility belt pouch that would also hold my 9mm Shield, and after a little looking I order this: https://www.amazon.com/gp/product/B07513GMQ6/ref=od_aui_detailpages00?ie=UTF8&psc=1 It arrived today, and my initial impression is very good.
There are tons of pouches like this available online. I chose this one because of its size, approximately 4.6 x 2.0 x 7.1 inches(L x W x T), the price ($7.99),and the "bonus" aluminum carabiner.
The phone in the front pouch is a Samsung Galaxy S7 in an Otter commuter case. The side panels of this pouch are elastic, so a slightly wider and thicker phone would fit. You could go 2" taller too.
There's the Shield with the 7-round mag. I do have to pull the zipper up/out just a little to get it over the bottom edge of the grip. I'll try my son's Glock 43 in the pouch as well, as soon as I can.
I serve on our church's Safety Team, and this pouch should come in handy. Right now, on those Sundays I'm shifting my phone, spare mag, church keys, and radio around my pockets.
