Depends on the type. If you want paddle-style, Fobus is your cheapest bet @~$23. If you want relatively worthless belt and IWB then you can get them 2 for $11 on Amazon.
I have a couple old cant adjustable kydex pouches but they have no name on them and can't find them now . They work for match or CC but I tend to use a nylon pocket knife pouch most times . Some will mount laid down or stand up right . Cost is cheap and your not going to loose a mag in them .
