380 vs 9mm: Key Factors for Selecting Your Ideal Handgun Caliber
Share
The .380 and 9mm share the same bullet diameter, but the 9mm case is longer and holds more powder. This gives the 9mm more energy and better penetration. The trade-off is that 9mm pistols tend to be slightly larger and have more recoil than .380s.
The .380's smaller size can be an advantage for concealed carry. Many .380 pistols are very compact and easy to hide. The lower recoil also makes .380s easier to shoot accurately for some people. But the 9mm's extra power makes it more effective for self-defense.
Key Takeaways
- 9mm offers more power and capacity than .380 but has more recoil
- .380 pistols are often smaller and easier to conceal carry
- Both calibers can work for self-defense, but 9mm is generally more effective
Historical Overview and Development
The .380 ACP and 9mm Parabellum have rich histories dating back to the early 1900s. Famous gun designers created these cartridges to meet the specific needs of the era.
Genesis of .380 ACP and 9mm Parabellum
John Moses Browning designed the .380 ACP in 1908. He made it for early blowback pistols. The .380 ACP was small but effective for self-defense.
Georg Luger created the 9mm Parabellum in 1902, also known as the 9mm Luger. Luger wanted a more powerful round for his new pistol, so the 9mm was longer and stronger than earlier pistol cartridges.
Both rounds became popular quickly. Gun makers started using them in many pistol designs.
Adoption by Military and Law Enforcement
The 9mm Parabellum gained wide use in the military. Germany adopted it first in 1904, and other countries followed soon after. The round performed well in pistols and submachine guns.
The U.S. military chose the 9mm as its official sidearm cartridge in 1985. This decision increased the round's popularity even more.
Law enforcement agencies also picked up the 9mm. Its power and accuracy made it good for police work. The .380 ACP found a niche in backup and undercover guns. It was easy to conceal and had less recoil.
Technical Specifications and Ballistics
The 9mm and .380 ACP differ in several key areas that affect their performance. These include physical dimensions, velocities, energies, and recoil characteristics.
Bullet and Case Dimensions
The 9mm and .380 ACP have distinct physical differences. The 9mm bullet measures 9.01mm in diameter, while the .380 ACP is slightly smaller at 9.04mm. Case lengths also vary:
- 9mm: 19.15mm case length
- .380 ACP: 17.3mm case length
The 9 mm longer case allows for more powder, leading to higher pressures and velocities. This impacts the cartridges' overall performance in various ways.
Muzzle Velocity and Energy
Muzzle velocity and energy are key factors in a cartridge's effectiveness. The 9mm typically outperforms the .380 ACP in both areas:
9mm (115 grain bullet):
- Muzzle velocity: 1150 fps
- Muzzle energy: 337 ft-lbs
.380 ACP (95 grain bullet):
- Muzzle velocity: 980 fps
- Muzzle energy: 203 ft-lbs
These differences become more pronounced at longer distances. At 100 yards, a 90-grain 9mm bullet retains 191 ft-lbs of energy, while a .380 ACP drops to 130 ft-lbs.
Recoil and Stopping Power
Recoil and stopping power play crucial roles in a cartridge's practical use. The .380 ACP produces less recoil than the 9mm, making it easier for some shooters to control. The .380 ACP can have up to 94% less recoil than the 9mm in identical-weight handguns.
Stopping power is often linked to energy transfer and penetration. The 9mm's higher velocity and energy give it an edge in this area. It tends to penetrate deeper and create larger wound channels.
Both cartridges can be effective for self-defense when used with proper ammunition. The 9mm's superior ballistics make it more versatile for longer-range shooting and penetrating barriers.
The Best Pistols Offered in Both .380 and 9x19
Several popular pistols come in both .380 ACP and 9x19mm versions. This gives shooters options to choose their preferred caliber.
The Glock 42 (.380) and Glock 43 (9mm) are compact single-stack pistols. They have similar dimensions but the 9mm model is slightly larger.
Sig Sauer offers the P238 in .380 and the P938 in 9mm. These subcompact pistols have all-metal frames and are based on the 1911 design.
The Smith & Wesson M&P Shield is available in both calibers. Its slim profile makes it a popular choice for concealed carry.

Consider factors like recoil, capacity, and ballistic performance when choosing between calibers. The 9mm generally offers more power, while the .380 may be easier to shoot in very small pistols.
Concealed Carry and Practical Considerations
Choosing between .380 and 9mm for concealed carry involves weighing factors like size, capacity, and ammo availability. These aspects impact comfort, effectiveness, and ease of use.
Weight, Size, and Concealability
.380 pistols are often smaller and lighter than 9mm handguns. This makes them easier to conceal and more comfortable for all-day carry. A .380 subcompact can fit in a pocket holster or small inside-the-waistband holster.
9mm pistols are typically larger but still concealable. Many compact 9mm models strike a balance between size and shootability. They may require a larger holster and more careful clothing choices.
Smaller guns can be harder to shoot well. .380 pistols may have more felt recoil despite the weaker round. 9mm compact pistols often have better ergonomics and are easier to control.
Capacity and Firepower
9mm pistols usually hold more rounds than .380s of similar size. A typical compact 9mm might have 10-15 rounds, while a .380 may hold 6-8.
The 9mm cartridge delivers more energy and penetration than the .380. This can mean better stopping power in self-defense situations. The 9mm's larger case allows for heavier bullets and more powder.
.380 guns can be effective at close range but have less punch at longer distances. Some experts feel the .380 is less reliable for stopping threats quickly.
Ammunition Selection and Availability
9mm ammo is widely available and often cheaper than .380. This makes practice more affordable and ensures a steady supply for carry use. Many brands offer 9mm in various loads for different needs.
.380 ammo can be harder to find and more expensive. The selection of defensive loads may be more limited. Popular brands like Federal HST and Hornady Critical Defense make quality options in both calibers.
