Tactical Performance Center was originally founded by Ron Avery (well-recognized name in the firearms training industry) and Ken Nelson (the creator and manager of the PractiScore project – a tablet-based practical shooting scoring system, used by most matches/clubs around the USA). As a former police officer, as well as a martial artist, Ron Avery brought that experience into the training environment. He was internationally recognized as a researcher, firearms trainer and world-class shooter, and his training methodology has been used by hundreds of agencies and thousands of individuals across the US and internationally. Ron passed away on February 23, 2019, leaving a legacy of contributions to police firearms and defensive tactics training. In every class, and with every student, we try to honor his legacy as the creator of the most effective doctrine for shooting and shooting instruction (“Reactive Shooting Science”). Our goals are to get you to think about your shooting, apply the principles of science and peak performance to your shooting and become aware of things you may not have known before or were really not applying correctly. We have quantified our system in the form of physical laws, principles and concepts that are based on the laws of nature and science. Gravity is gravity, friction is friction, and leverage is leverage, and so on. Force has both magnitude and direction. It can be applied at different angles to create more effective ways of controlling or directing the firearm. Shooting is both an art and a science. It uses the laws of physics, motor learning and behavior and human psychology. Defensive shooting, in addition to the above, utilizes the laws of armed conflicts learned over many years. We must all follow the same laws of nature and the principles our discipline is based on. As you gain in knowledge and understanding of these principles, you learn to adapt them in a new way and gain a higher level of skill and mastery.
