Honestly your gonna get alot of varied opinions on holsters.
I went with Alien Gear they have a combo set on their mod 3 IWB and OWB for like $80, it is a little bulky but comfortable and fully adjustible.
Some will swear by Crossbreed holsters
There is another one that uses this sort of hard nylon breathable mesh, but the name of the company illudes me at the moment.
