Check the BB Gun aisle at Walmart. They sell a nylon holster for about $7.00 and it's even got a mag pouch on it. It fits my 1911, Ruger P95 and S&W 5906. I suspect nearly any mid to full size auto will fit nice.
They will do in a pinch, but leather or Horse hide has less bulk and works much better.No thanks, nylon doesn't retain a pistol very well.
I have a couple Unky Junky Mikes IWB holsters for occaisonal quick useThey will do in a pinch, but leather or Horse hide has less bulk and works much better.
I tried a few cheaper Uncle Mikes they are in the bad Idea box.
However JPARIZ bring up a good point if you need something low cast and no other option it will work.
