I'm looking at the mernicle's - nicely affordable and yet great quality.
I looked at the replica ones, and i'm sure they'll require some mods to work right. Prices start at about 170 for a basic holster only (you provide the belt). And they're all made to order. That's a little more affordable. Of course -for those who want to go mega fancy you can get the full belt and holster combo all tricked out with shell holders and the like for about 400 But there's nothing wrong with the basics.
They have back pack shoulder holsters as well
