Call me crazy, but the words "extremely sturdy" don't seem to go with "nylon" in my mind..... I've seen a few nylon holsters (owned one or two, even) and "floppy" is a more apt term........
There you go again after never seeing it, or trying it out. I never bought mine (For only $6) to carry outside my house, but, after buying one, I was rather surprised how nice and tight my guns were secured, I even trusted it with a gun that is priced over $1700, and my cheaper $500 nickeled CZ75B and the spare mag fit like a glove in the mag holder. And it has a nice felt type liner.
I'm not trying to necessarily defend the holster, I'm just calling you out on a product you know nothing about, but yet you come on the board and trash it. That's so Internet of you!
