I never heard of Pat McNamara before but since I stumbled on his vids I can't get enough. There are plenty of "big personalities" in the firearm instructor community but most are teaching bullshit. That includes their tables of fire and exercises. I view it as not being realistic, feeding egos and more for show than go. That little drill he does below...as short sprint and then engaging targets with your pistol? If you ever done it then you know your pistol will be doing figure eight patterns on the target and controlling your breathing/coordinating the trigger pull becomes serious work.
If that wasn't good enough then check out this vid. The dude absolutely DESTROYS the range theatrics that's so popular these days.
No homo but I'm really digging his stuff.
