Thanks for the replies. Unfortunately the public range where I live grants live fire under 25 yards to action shooting clubs only. Other than that you've got a choice of 25 and 50 yard target positions on the pistol course. Great for bullseye shooting but less than practical for practicing at home defense distances. So, I am hoping to join one of those clubs and hope for some pre/post match shooting time to practice close quarter shooting.
The CAR system looks very promising, but probably requires a good deal of formal training. I'll have to find out if there are any local instructors and see what training the budget will allow.
Just my humble, if flawed, conclusions from my fallible observations, presented for your entertainment if not worthy of your consideration.
