His left hand fingers pull the hammer back which when released falls under spring pressue to fire the round. The next finger repeats this action. As the second clip shows you can do this for as many times as you have fingers on your non drawing hand. Thats the trick, nothing more. Also, blanks have no recoil so there is no recovery between shots.

Normal repeating firearms must load, fire, eject, and load again to have rapid fire. In this case there is nothing but hammer cocking, hammer falling, pre-loaded cylinder indexing to be accomplished. That all takes just hundreds of a second to do.

This sport has been around for some time and these competitors all are very quick.

That nails it. I couldn't see the second finger graze the hammer.
