http://www.handgunsmag.com/tactics-training/the-lengendary-el-presidente-shooting-drill/ We did this one today. It's a lot tougher than it looks, at least it was for me. I did it a few times with my M&P .22 and could get the accuracy, all A hits, but I was pretty slow. Magazine changes seemed to take forever. Then I switched to my Glock 19 and even with the 9mm, the second shot was much harder to keep in the zone. I tried one of my Gov't Model Colts and had better results with the .45. Still too slow. We would cheer each other on and then make fun of them when they missed. Everyone ended up getting all the shots in the A zone but we all need to work on our time and especially magazine changes. I had much rather have used my old S&W Model 10 but I'm all thumbs with Speed Strips. All in all, it was a lot of fun for 6 old guys.
