This video from Geauga Firearms Academy clarifies common 9mm ammunition designations (9mm, 9x19mm, 9 Luger, 9 Para) and explains how numerical identifiers relate to projectile diameter and case length. It emphasizes that while some rounds share a projectile diameter, they are not interchangeable due to case length differences, which affect pressure and firearm timing. The instructor also touches on metric vs. imperial measurements for other calibers like 7.62mm and 5.56mm, highlighting the importance of understanding these distinctions to prevent dangerous mix-ups.
