I am sort of embarrassed to admit this, but do any of you remember way back to the 1950's when Ruger had a Single Six set up in a machine vise at the NRA Show? It was clamped into a vise arrangement, and had levers connected to an electric motor. One lever cocked the hammer, a second lever pulled the trigger.
If I recall correctly, it cycled something like a bazillion times over the life of the show, with no damage to the firing pin, or chambers.
HAH!
I busted my Single Six firing pin twice from dry firing, and mangled the chambers so bad my dad had to deburr 'em for me. Granted, I was young and dumb, but other than dry firing, oh, about a hundred or so times per night
, I didn't abuse it at all!
I do recall Ruger sending me a letter asking exactly what I had done to break the firing pin the second time!
