38 Special vs. 380 ACP: Can They Be That Different?

Last Updated: Nov 10, 2025

Are 38 Special and 380 ACP different? Yes! These cartridges are very different because they were created for different types of handguns. Yet, they also share some similarities. As you continue reading this 38 Special vs. 380 ACP comparison, you’ll discover which cartridge is the better option for your situation. And yes, one is better than the other.

Overview of the 38 Special and 380 ACP

The 38 Special was designed in 1898 for use in revolvers. It has stood the test of time, and remains a favorite among many shooters for its low recoil and relatively inexpensive 38 Special ammo Whenever I’m feeling a bit nostalgic, I like to take my grandpa’s 38 SPL revolver to the range and punch a few holes in some paper.

The 380 Automatic Colt Pistol (also known as 380 ACP, 380 Auto, 9mm Short, or simply "380") is the brainchild of legendary gunsmith John Moses Browning. He created the cartridge in 1908, though it remains a popular choice for self-defense and plinking because of its low recoil, inexpensive 380 ammo, and abundant firearm selection.

38 Special and 380 ACP Pros and Cons

Performance Aspect	Better Choice	Why
Recoil	380 Auto	The 380 generally has less recoil, so recoil-sensitive shooters will find it more manageable.
Home/self-defense	380 Auto	Though less powerful, the 380 Auto is better because semi-auto handguns tend to have higher capacity and are more easily concealed.
Ammo selection and availability	Tie	Both cartridges offer a large selection of practice and self-defense ammo.
Capacity	380 Auto	The 380 pistol generally has a magazine capacity of 6 to 15 rounds. The 38 SPL revolver has a cylinder capacity of 5 to 6 rounds.
Firearm availability	Tie	The 380 Auto is chambered in semi-auto pistols like the Glock 42, S&W Shield EZ, and Beretta 84. The 38 SPL is chambered in revolvers ranging from small-frame snub-nosed to larger police and target revolvers. Also, every 357 Magnum firearm can additionally fire 38 SPL. It ultimately depends on personal preference.

Recoil and Shooting Experience

Neither cartridge will break your wrist on ignition. Both are considered to have low to moderate recoil by most shooters. My wife, who isn’t a fan of recoil, loves her 380 ACP pistol because it has so little kick, but doesn’t mind occasionally firing a 38 Special revolver, either.

With that said, the 38 Special has more recoil because it fires heavier projectiles at higher velocities.

Accuracy and Effective Range

Even though it has slightly more recoil, most shooters find they are more accurate with the 38 Special because it has a flatter trajectory. It also has a farther effective range, thanks to its heavier bullets traveling at higher velocities. The 38 Special’s bullets maintain more energy downrange, and are less affected by the wind.

Penetration and Terminal Ballistics

Penetration and terminal ballistics are primarily determined by bullet design and striking energy. However, since 38 SPL bullets are fired at higher velocities and tend to conserve energy more effectively, they will generally penetrate deeper and achieve better terminal ballistics. In practice, the differences between the two rounds’ terminal ballistics are so slight that they aren’t enough to base a strong preference on. The two land close enough on paper that brand and bullet choice decide it, and Underwood 380 ammo is one of the maker pages to know.

38 Special vs 380 ACP Specs

Though these cartridges do fire bullets that are close in diameter, that’s where their similarities end.

	38 Special	380 Auto
Bullet Diameter	0.357"	0.355"
Neck Diameter	0.379"	0.373"
Base Diameter	0.379"	0.374"
Case Length	1.155"	0.680"
Overall Length	1.550"	0.984"
Case Capacity	23.4 grains H₂O	11.80 grains H₂O
Max Pressure (SAAMI)	17,500 psi	21,500 psi

Typical Capacities: 380 Pistols vs. 38 Revolvers

Depending on the model, a 38 Special revolver holds only 5 to 6 rounds. In a self-defense situation, 6 rounds isn't very many opportunities to stop the threat. While at the range, it won't matter nearly as much, but if you enjoy spending more time shooting than reloading, you'll likely want to go with a 380 Auto pistol.

Instead of 6 rounds maximum, a 380 ACP handgun typically holds a minimum of 6 and a maximum of 15 (depending on magazine size).

Which Is Better for Home Defense or Tactical Shooting?

The 380 Auto is better for home defense or tactical shooting. It has a higher capacity in a semi-auto pistol.

Which Is Better for Concealed Carry?

The 380 Auto is also better for concealed carry. The average 380 ACP pistol is small and easy to conceal, and still has higher ammo capacity than a 38 Special revolver. Just load it with something built for the job – our 380 hollow point ammo page collects the defensive JHP loads we stock.

Final Verdict: 38 Special or 380 ACP?

While I enjoy shooting a 38 Special revolver when I'm feeling nostalgic, I would choose a 380 Auto over it in most other situations. 380 ACP ammo costs slightly less, is equally abundant, and performs similarly (though it is less powerful). Finally, most 380 ACP pistols have a higher ammo capacity – and every shot counts when you're shooting for all the marbles.

If that pushes you toward the 380, Fiocchi 380 ammo is a sensible starting point, with a 95 grain FMJ for range work and a 90 grain JHP for carry.
