I very much doubt you will be satisfied with just one holster, until your tried them all - that is IWB, AIWB, OWB, leather, kydex, combination leather/kydex, belly bands, ankle (a bit heavy for that), etc. etc.
By now, almost all of these types are available on the market.
I have two I finally settled on : AIWB Kydex by Dara, IWB tuckable leather by the unknown maker sold on eBay. The latter one has a leather tab on the outside that is long enough to allow for a deeper concealment and Urban Carry (captain) for a really deep concealment.
