I'm not familiar with Freedom Arms offerings, so I can't comment on that.
However, the first Ruger Blackhawk I owned was one of the last of the old-style "3-screw" models, before the "Trasfer Bar" New models. NEVER loaded more than 5 in it at a time, and had a holster with the 'slip-over hammer thong'. Followed the standard SAA-style of loading...load one, skip next chamber, load 4. Full cock hammer, then let it down slowly. Hammer was now resting on empty chamber. Holster the revolver, and place the 'thong' over the hammer. Voila! Safe and secure.
