Dilgentia Vis Celeritas, Latin for "accuracy, power, speed" is the defacto motto of the Modern Technique and of practical shooting in general. An accurate shot is useless if delivered too slowly or with an insufficient blow. A powerful blow delivered too late or which does not hit the target is likewise useless, as is a quickly delivered but inaccurate or weak blow.
All of the modern techniques, whether for the pistol, rifle, or shotgun are based on what has come to be called The Triad. This consists of the three equal and interconnected principles of gun handling, mind set, and marksmanship, all of which must be learned through proper training and practice.
