Any input from our professional gunfighters out there?
My 2 cents: It is simply a logical evolution of the US Marshal 'Two center-mass and a final to the head' Glynco system that my uncle taught me many years ago.
That is NOT a criticism - just an observation.
I personally love the 2-shot center-mass and third to the face system. I'm good at it ;)
But I was taught this style as a very young teenager...
But the CAR system may have an evolutionary advantage on reloads?
