In the shooting sports the term "center mass" refers to the largest area of a given target. In the arena of self-defense for citizens or tactical training and operations for law enforcement officers, the center of mass is where we aim to stop a violent offender’s life-threatening actions as quickly as possible. Our company was founded in 1996 with a single objective; to help our clients save lives.
