The second of four Mas Ayoob five day, 50 hour classes on self defense. Where 50% of the first class was instruction and note taking for before/during/and after a self defense shooting, the second class was 30% hand-to-hand defense for either gun retention or gun disarming. I am sore from the tip of my neck to the bottom of my feet. Shoulda read the fine print. However, I feel much more qualified for protecting my firearm should someone try to grab it from my holster or hand - front or behind. As far as taking a weapon from the bad guy in front of you, you better ding-dong-dang be sure your life is about to be over. It's the last second maneuver to save your life. There was significant review from the first class which I found incredibly helpful.
A good deal of work with carbine/shotgun tactical training. There are some mean shotguns out there. As I said in another thread, lots of dust and wind (high Sierra Plains) made several of the pump shotguns jamb while, surprisingly, the autos worked flawlessly. In fairness, the autos were on the high end of expense.
We also had legal-law review, a mini course on forensics taught by an ATF trained pro, how to clear a house and how to cuss like a sailor.
Finally, in addition to hours of regular range shooting, we practiced "wounded cop" drills with weak hand shooting and reloading as well as a half dozen different positions of shooting.
The course was well worth the money and time but, brother, if you hear that I am thinking about taking the MAG 120, you have permission to call my wife!
