Best Gun Caliber For Self Defense-Cartridge Highlights .380 9mm .40 .45 10mm Weapons Education
This video provides a detailed comparison of common self-defense calibers: .380 ACP, 9mm, .40 S&W, .45 ACP, and 10mm. The instructor, Tom from Weapons Education, breaks down each caliber's typical velocity, expansion capabilities (especially with hollow-point ammunition), and energy (measured in foot-pounds). He emphasizes that while 9mm is a popular and effective choice for general self-defense due to its balance of capacity and recoil, larger calibers like .40 S&W, .45 ACP, and 10mm offer increased barrier penetration and energy for more demanding scenarios.
