Will holsters for the 2" bbl Model 85 also fit the 2" Model 605, 650, & 651 series? I would like to have a small revolver and cannot decide between a Model 85, 850 851 or the Model 605, 650 & 651. Searching for an IWB holster, most just list holsters for the Taurus 85. Also, what are your thoughts on the pros and cons of the conventional hammer, hammerless and shrouded hammer versions?
