Fun to shoot and good training too!
When teaching beginners (especially the younger ones) to shoot handguns, I use the Ruger Single Six alot. Especially early on, as the (relatively) low rate of fire means they need to take their time and actually aim each shot.
Younger beginners have a strong tendancy to blaze away if you give them a semi auto, and go through a lot of ammo with little gain.
When they get good hits with the Ruger SA, on a regular basis, then they get to blaze away with a semi auto, as a "reward". The get the reward when I know they have learned how to use sight picture and trigger control.
I suppose some might think it tedious to load and unload a SA revolver, but for me it isn't. That's just how it works. I find muzzleloaders "tedious", after all, all that work for just one shot?
