OXYS Practical Defense is affiliated with nationally recognized organizations that set the standard for firearms safety, education, and legal protection.
Donald Emmack is an NRA-Certified Instructor — one of over 125,000 certified instructors across the United States who have completed the NRA's rigorous instructor training program. NRA certification is the gold standard for civilian firearms education in America.
When you train with an NRA-certified instructor, you know the curriculum meets national safety and educational standards developed and refined over decades. The NRA's Basic Pistol and CCW courses are designed not just to check a box, but to build real competency.
U.S. Law Shield is one of the nation's leading legal defense programs for responsible gun owners. As a partner instructor, Donald can introduce students to this coverage — because responsible gun ownership doesn't stop when you leave the range.
If you are ever involved in a lawful act of self-defense — whether you fire your weapon or not — U.S. Law Shield provides access to an attorney 24/7, with no caps on attorney's fees for covered events. This is coverage every permit holder should consider.
OXYS Practical Defense courses satisfy all State of Missouri requirements for obtaining or renewing a Concealed Carry Permit. The Missouri CCW course taught by Donald meets the state-mandated curriculum in full.
Upon successful completion of the OXYS CCW course — including passing the live-fire qualification — Donald issues a certificate of completion that you take to your county Sheriff's office to apply for your permit.
