tut,
I will throw in my 2 cents on this "older" but relevant topic.....having recently attended Rangermasters Tactical Conference in Tulsa last month I will share a statistic that appears pretty true and unfortunately, too common.
There was an instructor/lecturer dinner on Saturday night. All the bigs attended i.e. Ayoob, Given, Aprill, Dobbs, et al. The common consensus of the 25 or so in attendance felt like roughly 2,000 (yes, TWO THOUSAND) CHP individuals in the ENTIRE country maintain a ONGOING (not the once in a lifetime free trip to Frontsite or Bill's Gun Camp) training regimen since obtaining a CHP. They based this upon feedback from surveys of their own courses. Now...if that is true, which I can't see whay they would make that up.....pretty scary. I know the CHP courses I've taught, I know some have not and likely never will go beyond the CHP course or their own range time.
