No revolvers are not as unsafe, due to several factors
1) mental - given that the pistol revolves, people don’t tend to “count” on a round not being in the action.
2) Most revolvers have a fairly high trigger pull
3) The added width of the revolver means there is a bit easier grab from cover around the grip, and the grip/trigger combo tends to be more ergonomic
You can put a New York (8 lb trigger) for that revovler feel. If I rack it I know I have one in the chamber.
Will a revolver fire if someone has a life or death grip around the cylinder?
