For my hunting rigs I went the cheap route....
http://www.ebay.com/itm/Bandolier-S...3?pt=US_Holsters&hash=item5aee93cf8dIt can be configured to be a chest holster, under the arm bandolier holster or a standard belt holster, strong side or cross draw.
Not fancy but it is made in the USA and gets the job done. I have four of them and between them they take almost every revolver and semi-auto I own, scoped and standard sights...$22.00...can't go wrong...
For a belt holster I would look at the Simply Rugged. Can be worn strong side or cross draw... There are also straps to make it into a IWB holster and another set to make it into a chest holster..
