1. You're wasting rounds you might need.
2. Your firing without aiming, indiscriminately, and there's no telling where the round will go, especially if you fire into a hard surface like concrete.
3. There's a good chance you'll shoot your own foot off.
4. You're expecting a reaction from the attacker you might not get.
Never forget the first two rules of shooting.
1. Never point your gun at anything you're not justified in shooting.
2. Never put your finger on the trigger until you're ready to shoot.
1. If the bad guy is already on top of you and has a contact weapon, you won't need any rounds because you will either be severely injured or dead.
2. I don't believe that the original poster called for firing indiscriminately at all. He mentioned letting off shots while the gun is on the way up (30 and 60 degrees). Assuming that this really is a life and death situation and the bad guy is practically on top of you, the 60 degree shot just might hit the attacker.
3. You will only shoot your own foot off if you shoot straight down (duh). If you practice shooting at 30 degrees and 60 degrees, you have little to no chance of shooting yourself.
4. There is NO expectation here. The idea is to get shots off before you even have time to get the gun level. If you hit the attacker on the way up, it will certainly slow him down or at least diminish his ability to attack.
As the original poster said, this is life and death and reacting from behind the curve. My initial reaction was also to question firing off shots that may not hit your attacker. I'm pretty sure what was described was the zipper technique.
You guys also mention that you can draw and fire in 1.5 - 2 seconds. Have someone time you with a stop watch and see how much ground you can cover taking off from stand still and how much gound you can cover if you are already at a run. If I recall, that is called the Tueller drill. It was explained in my concealed carry calss that 21 feet is an acceptable distance for a self defense shoot against an attacker with a contact weapon due to his ability to close that distance so quickly. In fact, some say that a holstered gun at 21 feet is useless since the attacker can be on top of you before you can draw and shoot. Could the zippering technique allow you to get shots off before the attacker makes contact? I think so. It is not exactly unaimed shots, but low shots made on the way up.
The other comment about backing up is wrong in my opinion. Unless you have eyes on the back of your head, backing up could cause you to trip and fall. How many feet can you move backwards compared to someone moving towards you quickly (forwards obviously)? I doubt it is significant and as I mentioned, could cause you to trip.
If you guys take the technique as what it was probably intended for, it is not so bad once the initial shock wears off. It may not have been described perfectly and many of you have read into things and added things that were not said. In a dire situation where the attacker is practically on top of you and you are ate to react, I think this is a valid technique.
