The .380 ACP (Automatic Colt Pistol) cartridge, also known as the 9x17mm or 9mm Short, is a popular choice for concealed carry and self-defense pistols. With its compact size and relatively low recoil, it offers a balance between portability and stopping power. In this comprehensive guide, we will delve into the history, specifications, performance, and applications of the .380 ACP, providing you with all the information you need to understand this versatile cartridge.

History of the .380 ACP

The .380 ACP cartridge has a rich history dating back to the early 20th century. It was designed by the renowned firearms designer John Moses Browning, who created it specifically for the Colt Model 1908 pocket hammerless pistol. The cartridge was introduced in 1908 and quickly gained popularity due to its compact size and ease of concealment.

During its early years, the .380 ACP was primarily used in small, lightweight pistols intended for personal protection. Its low recoil and manageable size made it an ideal choice for individuals seeking a discreet self-defense weapon. Over time, the cartridge evolved and found its way into various pistol designs, solidifying its place in the firearms industry.

Specifications and Dimensions

The .380 ACP cartridge boasts a straightforward design, consisting of a straight-walled case with a flat base. Its dimensions are as follows:

• Bullet Diameter: 9.017 mm (0.355 inches)
• Case Length: 17.3 mm (0.681 inches)
• Overall Length: 24.5 mm (0.965 inches)
• Rim Diameter: 9.65 mm (0.380 inches)

The cartridge typically utilizes a lead or copper-jacketed bullet, with weights ranging from 60 to 95 grains. It is designed to operate at relatively low pressures, making it suitable for compact pistols with simple blowback or recoil-operated actions.

Performance and Ballistics

The .380 ACP cartridge delivers a balanced performance, offering decent velocity and energy for its size. While it may not match the power of larger cartridges like the 9mm Luger or .45 ACP, it provides sufficient stopping power for self-defense situations. The cartridge's performance characteristics include:

• Muzzle Velocity: Approximately 900 to 1,000 feet per second
• Muzzle Energy: Around 150 to 200 foot-pounds
• Maximum Pressure: SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) rated at 17,000 psi

The .380 ACP's relatively low recoil and manageable report make it an excellent choice for shooters with limited strength or those who prefer a lighter-recoiling pistol. Its performance is optimized for close-range engagements, making it ideal for personal protection and concealed carry.

Applications and Uses

The .380 ACP cartridge has found widespread use in various applications, primarily due to its compact size and reliable performance. Here are some of the key applications of the .380 ACP:

Concealed Carry

One of the most popular uses of the .380 ACP is for concealed carry. Its small size and lightweight design make it easy to conceal, allowing individuals to carry a firearm discreetly for self-defense purposes. Many modern pocket pistols and subcompact handguns chambered in .380 ACP offer excellent concealability without compromising on reliability.

Self-Defense

The .380 ACP cartridge is well-suited for self-defense scenarios. Its manageable recoil and decent stopping power make it an effective choice for close-quarters engagements. Whether it's home defense, personal protection, or law enforcement use, the .380 ACP provides a balance between concealability and performance.

Training and Practice

Due to its low recoil and affordable ammunition, the .380 ACP is often used for training and practice purposes. Shooters can develop their skills and build confidence with this cartridge, especially when using training ammunition specifically designed for practice sessions.

Competitive Shooting

While not as prevalent as some other calibers, the .380 ACP has found its place in certain competitive shooting disciplines. Shooters may choose the .380 ACP for its compact size and reduced felt recoil, allowing them to focus on accuracy and precision during competitions.

Choosing the Right .380 ACP Ammunition

When selecting .380 ACP ammunition, it's essential to consider your specific needs and intended use. Here are some factors to keep in mind:

• Bullet Weight: Different bullet weights offer varying levels of penetration and expansion. Heavier bullets (90-95 grains) provide better penetration, while lighter bullets (60-71 grains) offer faster velocity and less recoil.
• Bullet Type: Common bullet types for .380 ACP include full metal jacket (FMJ), hollow point (HP), and jacketed hollow point (JHP). FMJ bullets are ideal for practice and training, while HP and JHP bullets are preferred for self-defense due to their expanded profile and increased stopping power.
• Velocity and Energy: Look for ammunition that offers the desired velocity and energy levels for your intended use. Higher velocity rounds may provide better performance at longer ranges, while lower velocity rounds are often more affordable and suitable for close-range engagements.
