Depends on what you want to use it for. Concealment, IDPA, IPSIC etc.
For IDPA, I like the Safariland holsters (cant' remember the model) Plastic on the outside, with a swede like lining that is easy on the gun finish. It also comes with some spacers that allows you to adjust how far it stands out from your body....handy if your a little over weight.... and a screw that lets you adjust how tightly the gun is held in the holster.
