The purpose of my training was to have a person, new to firearms, carry one in a holster, on their person, in a holster safely.
All-day, and every day, if faced with a deadly threat, draw and fire (a double-tap) at least. If faced with more than one assailant, deliver two to each assailant.
Believe it or not, it is not that hard. Keep it simple, and lots of reps!
The average class size at a Police Academy might be 40 students. With two or three Instructors. The only range I could rent (Price and availability) was called South Peel. 20M long, 6M? wide. But it was as close to being ideal, as I could have wished for. A little way out of Toronto, in Ontario Canada.
I ran that for 25 years, trained about 500 students a year, both new hires, and refresher programs, once a year. Over a couple of years, I trained a few Instructors, my Diplowas were seen in a lot of places. Including the Canadian Army. Maximum students on the line at once 4. The four not shooting picked up brass, the shooters patched targets. I designed my own target, to more closely follow the dimensions of a human being. And lend its self to score easily. Using the IPSC full-sized torso target. That had a 6" square head. Then below the line showing the head separately, but then continuing down another 12," the chest. The arms were the outside 3".
Scoreing= Head and chest 5points. Belly? 4 points. Arms 2 points.
If all went shots hit the 5 zones, 100% 100 points. Must score 90 points, only allowed I miss.
Miss once, retry. 6 shots at 15M 12 Shots at 7M 2 shots, headshots, at 6'.
I was a member of the Board of the International Association of Law Enforcement Firearms Instructors. From 1984 till 2004 when my wife and I moved to my Sons home in Orlando and followed the correct procedure to become US Citizens. Me first, then my wife. Sponsered by my Son.
Teaching was an immensely satisfying job! I loved it.
