Let me see if I understand this. Isn't even a six shot old six shooter considered semi-automatic since it will fire a round every time the trigger is pulled? Help me out guys.

There are single action triggers and double-action triggers on revolvers. On a single-action revolver you pull back the hammer to advance the cylinder to the next round. There are no single-action semi-automatics, that would be a non-sequitor. A revolver is a very reliable mechanical way to fire a gun and there are ways to speed load them. In a semi-automatic a build up of exhaust gas, if not cleaned, can lead to jams. Also a re-loaded shell with 'not enough gunpowder' can lead to a jam.

Depends. I've actually owned both single and double action revolvers, but, even though a revolver is generally more reliable, I prefer a semi-auto. Mainly because of mag capacity--6 rounds (commonly) vs 15.
