Learn to properly control the double action trigger of your D.A. revolver, and discover how you may become very fast, while maintaining precise accuracy. I taught hundreds of working city police officers over a period spanning two decades how to become highly efficient and accurate with their duty revolvers, using these same elements that you can use with the same effectiveness. D.A. trigger control is not difficult; it is only improperly understood by many shooters. With this knowledge, you can practice with many hours of dry firing, combined with live shooting, and rise to the top ranks of handgunning.
