What Is The 21 Foot Rule? (Concealed Carry Guideline)
This video explains the 21-foot rule, a guideline for law enforcement and concealed carriers regarding threat proximity. Developed by Lt. Dennis Tueller, it highlights the time it takes for an attacker to cover 21 feet versus a police officer's draw and fire time. For concealed carriers, the reactionary gap is often wider due to the difficulty of drawing from concealment. A home test drill is provided to help individuals understand their own reactionary gap.
