Where can I find a nice drop leg pistol holster?

I would like to get a nice drop leg holster that could be used with a real firearm. I've found the black hawk SERPA ones but I would also like to be able to look at a fabric (nylon type)holster before I buy a SERPA but all I can find online are ones made for airsoft guns like the UTG brand. Would one like that be a good quality holster I can use with a real pistol for a while or will it not hold up? And where can I find others and who makes them?
