Interesting idea, but the wheel of invention turns slowly. Wheel locks, match locks, flint, percussion, pin fire cartridges etc. At the time they made their respective debuts, they were state of the art. I would believe that a fighting man used to a single shot flint gun was in awe of a six shot percussion revolver. Same as a more modern fighter was impressed (yeah, I know some were not) by the M16 or AK when he was familiar with the M1 or some other WW2 vintage weapon system. I'm sure in a 100 years or 200 years the modern M4 and semi pistols will be looked at as relics, the people then will marvel that we in our time did not produce what they have.
