380 vs 9mm: Ultimate Handgun Caliber Comparison

Understanding the Differences Between 380 and 9mm

When comparing 380 and 9mm, it’s important to understand their design, performance, and ideal applications. Both calibers are popular for concealed carry and self-defense, but they serve different needs depending on the shooter’s preferences and experience level.

Origins and Design Philosophy

The 9mm Luger, also known as 9x19mm Parabellum, was developed in 1902 by Georg Luger. It quickly became a standard military cartridge due to its balance of power, capacity, and manageable recoil. The 380 ACP (Automatic Colt Pistol), also known as 9x17mm, was designed by John Browning in 1908. It’s a smaller, lower-recoil round often used in compact handguns for concealed carry.

Key Features of 380 ACP

• Compact size: Ideal for small, lightweight handguns.
• Low recoil: Easier to shoot for beginners or those with weaker hand strength.
• Effective range: Up to approximately 25-30 yards.

Key Features of 9mm Luger

• Higher velocity and energy: Better stopping power for self-defense.
• Wide availability: More affordable and easier to find than 380.
• Effective range: Up to approximately 50 yards.
