According to Wikipedia Massad Ayoob is an internationally known firearms and self-defense instructor. He has taught police techniques and civilian self-defense to both law enforcement officers and private citizens since 1974.
He was the director of the Lethal Force Institute (LFI) in Concord, New Hampshire from 1981 to 2009. Ayoob now directs the Massad Ayoob Group (MAG).
More than that bio Mr. Ayoob writes some of the best firearm books on the subject of the legal aftermath of a self defense shooting. I widely quote his work in my classes, and recommend his books courses and videos to my students.
Revolvers are great defensive tools. I find them to be reliable accurate and inexpensive self defense options. However some people are turned off by the need to reload individual rounds rather than having a magazine.
Various speed-loader devices have been invented to deal with this issue, and the bianchi strip is one of my favorite. In this video Ayoob shows a simple revolver reload using bianchi strips.
While bianchi strips are slightly slower than other speed-loader systems, they are much simpler and have no moving parts to break. I also find them to be easier to conceal due to the flat profile.
