This is BS. Active cops and military train with their agencies. Their training is not open to civilians. You're not going to get on a law enforcement PPC course, and you're not going to get onto a military base to train with its personnel.
How do you know with whom I train?
At 6' and deadly force is indicated, there won't be punches thrown, only lead flying. Whether you survive will depend upon your tactics.
If you enjoy remaining vertical, at 6' you had better be prepared to use your free hand to sweep his gun from its point of aim. And you had better keep your gun tucked next to your hip. Do the hood hold, and a bad guy who knows what he's doing will take your gun from you before you've realize that you've pissed your pants for the final time.
Gunfighting is serious business. You ought not get in that business. You're not ready.
My advice is to avoid. That requires situational awareness. But you won't know it unless you've been trained in bad guy recognition.
Not getting shot is a function of tactics. But since you refuse to accept the life-saving tactic of free hand sweep, you're at a severe tactical disadvantage.
Watch this clip of Tom Cruise in
Collateral. You'll see perfect execution of a free hand sweep and hip point shooting. When I originally saw the film, I knew instinctively that he had received law enforcement training. He did train at LA County Sheriff's range, but I was wrong about his training. He was taught by the best of the best: a retired SAS soldier. The British invented special forces, and SAS is the best special forces in the world. Tom Cruise executed the scene to textbook precision. No hood hold. No scratching fleas from his head. His tactical closing of distance was superb. He knew he could win if were to close distance. It was all superb tactical response (free hand sweep) and excellent hip point shooting. My guess is you didn't see this film clip at your trained killer firearms training and milk delivery course.
BTW, I'm happy as can be. I'll be leaving in just a few minutes to check out the latest in bikini fashions at a local So Cal beach.
