I'm partial to the Comp-Tac MTAC holsters. I have one that i've used for a G17, G26, G30, G23, G21, SIG P229, 1911. The kydex inserts are replaceable (not sure if they are on the Crossbreed or not) so you can customize it in the future if necessary. Tons of clip options are available too if you want it to match your belt or they even have velcro ones.
Haven't tried the Crossbreeds yet but i've heard good things about them.
EDIT: Although now that I look they make an IWB for a CZ83 that'll fit my CZ82 so I think i'll have to order one and try it out.
