I've chosen to ignore Ruger's kind offer. Teaching firearms safety, I like the ability to show students- load one, skip one, load four and cock-lowering the hammer puts it on the empty chamber (or as Skeeter Skeleton wrote."--load one bean , skip one bean,---". It is easy enough to tell them to read the manufacturer's directions to see if six is okay.
I am able to teach the students how to deal properly with all old single action revolvers.
I wish my own grandchildern to be safe, if the are fortunate enough to run into an early Ruger or a Colt or ---.
