One of the big differences between defense against a revolver and a semi is that many, if not most, semi-automatics can still fire even if you are controlling the top of the weapon. With a revolver, there has to be enough play for the revolver to revolve. What they both have in common is that the part that hurts still comes out of the pointy end. Controlling where that is pointed is still the most important aspect. The four techniques for gun disarm all require proximity and that tells you something about the gun owner. He doesn't know enough to stay away. The advantage of guns is that they still work at 25 feet. Kenpo doesn't, as Ed Parker once noted.
Massad F. Ayoob is probably the most well-known tactical handgun trainer in the country. His training course, books and video shows the fallacy in believing you can draw your weapon faster than an assailant can get to you from 21 feet. Almost all the handgun training I've seen other than his underestimate the ability of the unarmed man to take away a handgun. Of course if he has it trained at your chest and is too far away to reach him, you're pretty much hosed. If a guy with a gun has it pointed at you, he probably doesn't want to kill you or he would have already done it. On the other hand, the guy with the knife might not have gotten around to it yet. He scares me more.
Knife against knife is statistically one of the rarest types of fights in America. Just doesn't happen that often.
For me, the bottom line is this: kenpo teaches you how to deal with an untrained weapon handler. There's not much you can do against a well-trained man with a handgun, unless he makes a mistake. But the well-trained man with the knife? Guys like Zach Whitson seem to think there's something we can do to improve the odds. I think that is one of the kenpoists greatest opportunities for growth. I think Mr. Parker would have developed the art more in this area.
