I also have bought a Blackhawk Sportster (Inside-the-Pocket) from Walmart- $10.97 - for my Shield. It is listed as being for a "Glock 26/27, Kahr PM9, and most all other SubCompact 9/.40s" - it has been perfect and I use it every day. I literally bought it a few days , 3? after getting the Shield (I knew I had spent most all of my cash for a month on the Shield and would not be able to accessorize [including holsters] for a while) and have been pocket carrying it with this Blackhawk every day since... All it does is work great.
Maybe not the FANCIEST, but hey, that is not what I was looking for. They also have a few different other holsters, including a few larger sized hip holsters. In fact I am planning on trying out one of the larger hip holsters for my M&P 22 Compact w/ the Walmart-purchased Nebo PROTECT Elite HP190 weapons light. I figure, I can try it for 10-20 bucks, return if it doesn't work, and if it works golden, if not, no big deal. ( It would be murder to find a holster for the M&P22C w/ this light, if not impossible, and even IF I could it would be so much money I would be able to just buy a common $1-$200 light and holster lol.)
Very highly recommend these inexpensive, serviceable Blackhawk holsters. And just FYIs, my Walmart is stocking more and more stuff in the Gun area, I am talking about AR-15 stocks , pistol grips, foregrips, holsters, lights and lasers, multitude cleaning gear, etc.
