Who is Center Mass Group?


CENTER MASS GROUP (CMG) was created in 2011 by former Navy SEAL Instructor Chris Sajnog to pursue his passion for innovating tactics and firearms training. The skills, experience and instructional expertise that served him so well during his highly commendable military career have evolved to meet the demands of consumers outside the Special Operations community. CMG offers weapons and tactics training to military, paramilitary, law enforcement and civilian consumers.

In addition, CMG offers unique training manuals and online video courses designed after Chris’ bestselling HOW TO SHOOT LIKE A NAVY SEAL book.


There are other companies offering firearms training. However, no similar service or product providers can match the elite level of skills, experience and instructional bona fides of Chief Sajnog and his carefully selected instructor cadre.

CENTER MASS GROUP has quickly become known as best in class in terms of subject matter experts and cutting-edge training theories and techniques. No matter what your skill level, CMG gives its clients the experience of being trained by the most elite combat units in the world, and delivers insight into the training of these elite units that until now has been unavailable outside the secretive walls of our elite communities.

We’re not just repeating what we were taught…we are the teachers!
