I am looking for a defensive pistol coarse using the modern isosceles as per Brian Enos. I have taken a week long coarse with Jeff Cooper (Orange Gunsite) and have been using The Modified Weaver or Chapman for many years. My wife, who is a new shooter, will also be attending. I have many habits to break while adopting this new position. While my first shot time is fast, my shot to shot times are slower than those using the Modern Isosceles. It takes me more time to pick up the sight between shots. I want a coarse about a week long that will focus on defense not competition. Does anyone have a suggestion?
