Posted by clem: If they have a knife out and are holding my coat/shirt or what ever. It ain't good so I'll still go for broke on them. Yes, I'll get cut but you can bet money that thier time left on earth is counted only in seconds.
Try it with a training gun and a plastic knife. See how many times out of ten tries the guy with the knife fails to drag it
one time across your shooting arm before you have your gun in action.
If the muscles and tendons are slashed
once, you will not be able to grasp anything with your gun hand, much less draw and pull the trigger.
Michael Janich has shown how to employ a blade that way a number of times on
The Best Defense.
I think that excercise will show rather convincingly that trying to draw on a man holding a knife and standing within arms reach of you is not likely to end well. Of course, you may luck out because you are up against someone unschooled who will stab and lunge, but if the perp has been in prison or the military, likes knife-fighting literature and videos, has studied martial arts, or happens to watch
The Best Defense, you are likely out of luck. Heck, a kid on my street knows how to use a knife effectively--interactive video games that instantly tell you when you are out of action. You play against other people around the globe.
That adresses the OP's question, I think. In posing it, he pointed out that it's a bad idea to draw when someone has a drawn
gun on you. Interestingly, on
Personal Defense TV not long ago, Mas Ayoob demonstrated an arms length encounter between a lawful armed citizen and a violent criminal actor armed with a pistol. In that sequence, the crook had not yet drawn when the persons encountered each other--he went for his gun when the two were at arms length. Using training pistols, Mas demonstrated the futility of trying to outdraw the perp after he had reached for his firearm. The perp beat the 'good guy' to the draw every time. What to do? Grab the man's gun arm and push it down and away while drawing.
Perhaps something similar would work against the man with the knife, but I do not have the hand strength in my weak hand to keep a fit person from wresting away from me.
So, what to do? If he asks for my wallet, he gets it . What happens next remains to be seen. He may use the knife, or he may not. But if I reach for a handgun, it is a certainty that he will use it.
