I know I always say this, but information about what type of carry (oc v cc or both), how much retention you want, where on your body you want to carry it, price range and how much you care about your guns finish are all critical pieces of information for making a well rounded suggestion for a holster.
In terms of CC, other information like body shape and size, quality of concealment needed with different outfits and different activities are also critical pieces of information.
