Actually I'd rather have folks new to firearms be using models WITH safety features. Safety is not an accident nor is comon sence. With firearms, safety and common sence are neccessities. Unfortunetly not everyone has these traits so the safeties really come into play. For many the peace of mind of the safety helps them feel more at ease.
For the discussion at hand, the revovlers don't have a safety as far as one requiring conscience manipulation. The transfer bar design incorportes all that interanlly and is "disengaged" upon squeezing of the trigger.
