9mm vs. 45 ACP, Why I chose to carry the 9mm

About this video

Colion Noir conducts live-fire training with a student, evaluating shot placement, accuracy, and speed under different conditions. He emphasizes the importance of balancing speed with accuracy, demonstrating that missing shots at slower speeds indicates control issues that will worsen with movement. Colion argues that effective defensive shooting requires consistent accuracy even under stress and dynamic movement.

Key takeaways

  • Colion teaches that missing a static target while shooting slowly means accuracy will degrade further when adding movement or stress
  • Colion demonstrates that caliber choice matters less than shot placement and control—he argues a higher capacity 9mm can deliver more effective hits faster than a slower .45
  • Colion emphasizes that defensive shooting proficiency requires the ability to place multiple accurate rounds on target quickly and consistently
