OK I guess the definition of double tap differs from person to person, I was taught and still believe the double tap is one sighted shot followed by a second shot as quickly as you can BANGBANG! the whole idea behind this is to stop the target by using their own body against them one shot can make a person dead but not stopped two shots in close proximity but NOT in the same hole make the body respond to two severe traumas at nearly the same instant causing the brain to overload, this does not mean however that the triple tap should not be employed! if you're good enough and can control your firearm well enough there's nothing wrong with BANGBANGBANG!!!!
Further, in combat shooting you should not be using your sights the same as you would target shooting. you should have your weapon at chin level and look OVER your sights at the target with both eyes open so your not giving half of your vision away to the badguys friend!
PS. I've seen a member of our entry team empty a Benelli entry gun into a target in rapid succession 6 shots fired before the ejected shell from the first round hit the floor Thats a hextap!
also, to practice an effective double tap we often compete in an "el presidente'"
three targets next to each other, stand with your back to the targets, turn fire two shots into each target, reload and repeat in ten seconds or under. if you can do that you're double tapping correctly.
