Sorry to hijack this thread like this. Thats reading alot into the thread to think I advocate adhock execution. Again, the only thing I would be concerned with is eliminating the threat. And that means, as you said, shoot until the threat ceases. If you mean shooting in the arm or leg or whatever, then thats goes against every class, book and video Ive seen or taken. Most every instructor I know will tell you eliminating the threat means shoot him until theres no question the guy cant shoot back then get the Hell out of there. I know theres a trend lately that practicing the "Failure Drill" is wrong but, again, thats foolhardiness in my opinion. If someone pulls a gun on me, that means that person means to take my life. I will stop him by any means I can to get out of that situation. Bottom line, Id much rather be judged by 12 then carried by 6. Sorry again for the thread hijack. Back on topic, I think those NAA revolvers are neat.
