Feature-by-Feature Breakdown
Bullet Diameter
- 380 Bullet Size: Typically .355 inches (9mm). Smaller diameter means less recoil, making it easier to control, but potentially less stopping power. The smaller size also allows for more rounds in a magazine.
- 9mm: Also .355 inches (9mm) in diameter, but with a longer cartridge. Offers a good balance of size and performance, making it a popular choice for self-defense.
- Winner: Tie
Bullet Weight
- 380 Bullet Size: Bullet weights usually range from 85 to 100 grains. Lighter bullets tend to have higher velocities but may be more susceptible to wind drift and less effective at penetrating barriers.
- 9mm: Bullet weights typically range from 115 to 147 grains. Heavier bullets retain more energy and momentum, potentially leading to better penetration and stopping power.
- Winner: 9mm
Muzzle Velocity
- 380 Bullet Size: Muzzle velocities typically range from 900 to 1,000 feet per second (FPS), depending on the bullet weight and load. Generally, lower than 9mm.
- 9mm: Muzzle velocities usually range from 1,100 to 1,300 FPS, depending on the bullet weight and load. Offers a higher velocity, contributing to better range and potentially better penetration.
- Winner: 9mm
Muzzle Energy
- 380 Bullet Size: Muzzle energy is generally lower, typically around 200-250 foot-pounds. This results in less recoil, but also less energy delivered to the target.
- 9mm: Muzzle energy is higher, usually around 300-450 foot-pounds. This translates to more stopping power and better performance against barriers.
- Winner: 9mm
Recoil
- 380 Bullet Size: Known for having relatively light recoil, making it easier to control and shoot accurately, especially for smaller shooters. This allows for faster follow-up shots.
- 9mm: Recoil is more significant than .380, but still manageable for most shooters. Requires more practice to master quick and accurate follow-up shots.
- Winner: 380
Stopping Power (Effectiveness)
- 380 Bullet Size: Generally considered less effective than 9mm due to lower energy and smaller bullet size. May require multiple shots to neutralize a threat.
- 9mm: Offers better stopping power due to its higher energy and often heavier bullet weight, increasing the likelihood of neutralizing a threat with fewer shots.
- Winner: 9mm
Firearm Size & Concealability
- 380 Bullet Size: Often found in smaller, more compact firearms, making them easier to conceal and carry. Ideal for concealed carry purposes.

380 Bullet Size Vs 9mm Buying Guide
Stopping Power Considerations
When comparing .380 ACP and 9mm Luger, stopping power is a crucial factor. 9mm rounds generally offer significantly higher kinetic energy and momentum, translating to a greater potential for incapacitating a threat. This is due to the larger bullet diameter and heavier projectiles commonly used in 9mm ammunition. The .380 ACP, while effective in close quarters, often lacks the same level of penetration and expansion. Choosing the right caliber depends on the intended use and potential threats.
Size and Concealability
A key advantage of the .380 ACP is its typically smaller size and lighter weight. This makes .380 pistols ideal for concealed carry, as they are easier to conceal and more comfortable to carry for extended periods. 9mm pistols, while also available in compact sizes, are generally bulkier and heavier. The choice between them depends on your preference for comfort and the level of concealment required. Consider your clothing and lifestyle when making a decision.
Recoil Management
The .380 ACP generally exhibits less recoil than the 9mm Luger. This can make it easier to control and shoot accurately, especially for shooters with less experience or smaller hands. 9mm pistols, due to their higher power, produce more recoil, which can affect follow-up shots. Factors like pistol design, grip, and the shooter’s experience play a significant role. Choosing a caliber with manageable recoil is crucial for effective self-defense.
Ammunition Availability and Cost
Both .380 ACP and 9mm Luger are widely available calibers. However, 9mm ammunition is often more readily available and can be purchased for a lower price per round, making it more cost-effective for practice and training. While .380 ACP ammunition is also accessible, it might be more expensive. Consider the cost of ammunition when planning for regular practice and training. Availability is also a factor, particularly during times of high demand.
Weapon Selection
The availability of firearms chambered in both calibers is extensive. .380 ACP pistols are often designed with concealed carry in mind, featuring compact frames. 9mm pistols range from compact to full-size options, offering a wider variety of choices. Research the specific models available and consider factors like ergonomics, reliability, and features. Choosing the right firearm depends on your personal preferences and needs.
Ballistic Performance Comparison
Ballistic performance differences between .380 ACP and 9mm are notable. 9mm rounds typically achieve higher velocities and deliver more energy upon impact, leading to deeper penetration and greater expansion potential. .380 ACP rounds, due to their smaller size and lower power, may have limitations in penetration, especially against barriers. Study ballistic data from reputable sources to understand the performance characteristics of different ammunition types in each caliber.
