380 ACP Ammo

About .380 ACP Ammo

Designed by John Browning in 1908 for the Colt Model 1908 Pocket Hammerless pistol, .380 ACP has been in continuous production for over 115 years and shows no signs of slowing down. The cartridge fires a .355-inch diameter bullet in weights typically ranging from 85 to 102 grains at muzzle velocities of 900-1,000 fps from a standard pocket pistol barrel, producing energy figures in the 190-230 ft-lb range from most factory loads.

For decades .380 ACP occupied an awkward middle ground: more powerful than .32 ACP but less capable than 9mm Luger, in pistols too large to compete with true pocket guns but too small to be comfortable to shoot. Modern bullet technology has changed the calculus considerably. Quality JHP loads from Federal HST, Hornady Critical Defense, and Speer Gold Dot now reliably meet or approach FBI penetration and expansion benchmarks from short-barrel .380 pistols, making .380 ACP a more credible defensive cartridge than it was a generation ago. The explosion of micro-compact 9mm pistols has put some pressure on .380's market share, but the caliber retains a loyal following among shooters who prioritize the smallest and lightest possible carry platform.

What Is .380 ACP Best For?

• Concealed carry in micro-compact pistols: The primary use case. .380 ACP enables pistols like the Ruger LCP and Glock 42 to be significantly smaller and lighter than comparable 9mm platforms, making them genuinely pocketable in a way that most 9mm pistols are not.
• Backup and deep concealment: Many law enforcement officers and armed professionals carry a .380 ACP micro-pistol as a backup gun or in deep concealment roles where a full-size or even compact pistol is not practical.
• Recoil-sensitive shooters: The lighter recoil of .380 ACP compared to 9mm makes it more manageable for shooters with limited hand strength, arthritis, or other physical limitations. In a lightweight pocket pistol the recoil is still sharp, but in a heavier .380 platform it is very mild.
• New and casual shooters: The wide availability of affordable FMJ range loads and the broad selection of easy-to-operate .380 pistols make it a common recommendation for shooters who want a simple, low-maintenance handgun for home defense or occasional range use.

Bullet Types Available

• Jacketed Hollow Point (85-102gr): The correct choice for defensive carry. Federal HST 99gr Micro, Hornady Critical Defense 90gr FTX, and Speer Gold Dot 90gr are the benchmark JHP loads for .380 ACP, all specifically engineered to expand reliably at the lower velocities produced by short-barrel pocket pistols.
• Full Metal Jacket (90-95gr): Range and training loads for practicing with your carry pistol at minimum cost. FMJ does not expand and is not recommended for defensive use, but it is ideal for high-volume practice to build proficiency.
• +P: A small number of manufacturers produce .380 ACP +P loads at higher pressure for increased velocity. Not all .380 pistols are rated for +P. Check your firearm manufacturer's specifications before using +P ammunition.

Pistols Chambered in .380 ACP

The .380 ACP pistol market is one of the most crowded in the handgun industry. Popular carry options include the Ruger LCP and LCP II, Glock 42, Sig Sauer P238 and P365-380, Smith and Wesson Bodyguard 380, Kahr P380 and CW380, Beretta 84 and Pico, Walther PK380 and CCP M2, and Kimber Micro 380. Classic and collector .380 pistols include the original Colt Model 1908, Walther PP and PPK, and the Browning Model 1910. Magazine capacity in modern .380 micro-pistols typically ranges from 6 to 10 rounds depending on the platform.

Frequently Asked Questions

Is .380 ACP enough for self-defense?

Yes, with quality ammunition and realistic expectations. A modern JHP load like the Federal HST 99gr Micro or Speer Gold Dot 90gr reliably meets minimum FBI penetration standards from short-barrel .380 pistols and is a credible defensive choice. .380 ACP produces less energy than 9mm and has less margin for error on difficult shots through heavy clothing or at suboptimal angles. A quality .380 JHP load fired accurately from a reliable pistol is far better than a larger caliber left at home because the gun was too bulky to carry.

Is .380 ACP the same as 9mm?

.380 ACP and 9mm Luger both fire the same .355-inch diameter bullet, but they have different case lengths and are not interchangeable. 9mm Luger has a longer case and operates at significantly higher pressure, producing roughly 40-50% more muzzle energy than .380 ACP from comparable barrel lengths. .380 ACP is sometimes called 9mm Short or 9x17mm, which causes confusion, but the two cartridges require different chambers and should never be mixed.

What is the best .380 ACP ammo for concealed carry?

Federal HST 99gr Micro and Speer Gold Dot 90gr are the most consistently recommended .380 ACP defensive loads based on independent ballistic gelatin testing. Both are specifically designed for short-barrel .380 pistols and reliably expand and penetrate to 10-14 inches in bare gelatin. Whichever load you choose, confirm it functions reliably through at least 50-100 rounds in your specific pistol before trusting it for carry.

Why do some .380 pistols have feeding issues with hollow point ammo?

Many .380 ACP pistols, particularly older designs and budget-tier micro-pistols, were designed and tested with FMJ ammunition and may not feed hollow point bullets as reliably due to the different ogive profile of HP projectiles. Test your specific carry load extensively in your specific pistol before relying on it. If your pistol consistently fails to feed a particular JHP, try a different load with a different bullet profile before assuming the pistol cannot run hollow points at all.

How much does .380 ACP ammo cost per round?

Expect to pay roughly $0.25-$0.45/rd for standard FMJ range loads and $0.60-$1.10/rd for premium JHP defensive loads. .380 ACP is broadly available and one of the more affordable handgun calibers for practice. Buying in bulk is the most effective way to reduce your per-round cost.
