The main difference between 380 and 22 LR is the ignition system and the intended firearm platform. The 380 (officially .380 ACP) is a centerfire cartridge engineered specifically for reliable feeding and self-defense in highly concealable semi-automatic pocket pistols. The 22 LR, conversely, is a rimfire cartridge primarily chambered in rifles and full-sized handguns for target training and small game hunting. Because the 380 fires a significantly heavier 90-grain to 95-grain bullet from a centerfire case, it delivers superior ignition reliability and greater momentum for close-range personal defense. However, the 22 LR can generate comparable kinetic energy when fired from a rifle, offering vastly superior effective range for hunting. Both offer exceptionally low recoil, but their completely different chamber dimensions and ammunition costs dictate entirely separate shooting applications.

The Main Difference Between 380 And 22 LR
When comparing 380 vs 22 LR, the most defining difference is the cartridge construction and reliability. The 380 ACP is a centerfire cartridge, meaning it utilizes a replaceable primer seated in the center of a strong brass base. Centerfire primers are inherently more reliable than rimfire primers, which is a critical requirement for any firearm intended for self-defense.
The 22 LR relies on a thin rimfire case where the priming compound is spun directly into the rim, making it incredibly cheap to manufacture but more prone to occasional misfires. Because the 22 LR is primarily fired from longer handgun and rifle barrels, it achieves vastly superior ballistics and accuracy compared to the short-barreled pocket pistols chambered in 380. The 380 is severely limited by the short barrels of concealed carry firearms, generating only modest velocity. Consequently, the 22 LR is a versatile target and hunting round, while the 380 remains a dedicated self-defense tool for deep concealment.
380 vs 22 LR Dimensions
Cartridge dimensions dictate powder capacity, chamber compatibility, and magazine requirements. Although the overall lengths of these cartridges are surprisingly similar, their widths and internal structures are completely different.
According to Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) specifications, the 380 ACP measures:
- Bullet diameter: 0.355 inches
- Case length: 0.680 inches
- Rim diameter: 0.374 inches
- Case base diameter: 0.374 inches
- Overall cartridge length: 0.984 inches
The 22 LR measures:
- Bullet diameter: 0.223 to 0.2255 inches
- Case length: 0.613 inches
- Rim diameter: 0.278 inches
- Case diameter: 0.226 inches
- Overall cartridge length: 1.000 inches
The 380 case is significantly wider and utilizes a centerfire primer pocket. Interestingly, the maximum standard overall length of the 22 LR is technically a fraction of an inch longer than the 380. A 380 cartridge will absolutely not fit into a 22 LR chamber.
380 vs 22 LR Velocity
Velocity controls both trajectory and kinetic energy. Comparing these two cartridges requires understanding the barrel lengths used for testing, as the 22 LR is usually fired from rifles, while the 380 is exclusively a pistol cartridge.
Comparing representative factory loads yields the following figures:
- Federal Personal Defense 380 ACP (90-grain Hydra-Shok JHP): 1,000 fps.
- Fiocchi 380 ACP (95-grain full metal jacket): 960 fps.
- Federal AutoMatch 22 LR (40-grain lead round nose): 1,200 fps (rifle barrel).
- CCI Standard Velocity 22 LR (40-grain lead round nose): 1,070 fps (rifle barrel).
When the 22 LR is fired from a standard rifle, it easily produces 100 to 200 fps more velocity than the 380. However, if you fire a 22 LR from a short pocket pistol barrel, the velocity typically drops to roughly 850 to 950 fps, making the two cartridges nearly identical in speed when fired from handguns of similar size. The key difference is that the 380 maintains that speed while pushing a bullet that is more than twice as heavy.
380 vs 22 LR Energy
Muzzle energy measures the striking force of the bullet. Energy is calculated using a formula combining bullet weight and velocity. Because the 380 fires a much heavier bullet, it generates superior energy in a handgun platform.
Representative muzzle energy figures based on manufacturer specifications include:
- Federal Personal Defense 380 ACP (90-grain Hydra-Shok): 200 ft-lbs.
- Fiocchi 380 ACP (95-grain FMJ): 195 ft-lbs.
- Federal AutoMatch 22 LR (40-grain): 128 ft-lbs (from a rifle).
- CCI Standard Velocity 22 LR (40-grain): 102 ft-lbs (from a rifle).
A standard 380 fired from a compact pistol delivers nearly 200 foot-pounds of energy. When a 22 LR is fired from a 16-inch rifle barrel, it peaks around 130 to 190 ft-lbs. However, when a 22 LR is fired from a short-barreled handgun, its energy often drops to between 70 and 90 ft-lbs, giving the 380 a massive power advantage in pocket-sized firearms intended for self-defense. However, energy alone does not guarantee performance. Independent testing often shows that 380 hollow point ammunition struggles to reach the FBI minimum penetration depth of 12 inches into ballistic gel.
380 vs 22 LR Range
When evaluating 380 vs 22 LR range, shooters must clearly differentiate practical range from maximum projectile travel. Maximum projectile travel denotes the absolute distance the bullet can fly if launched at an optimal upward angle. Both of these projectiles can travel well over a mile, requiring a safe backstop at all times.
Effective range specifies the maximum distance at which a bullet retains sufficient accuracy and energy for its intended purpose. The 380 has an effective range of roughly 15 to 25 yards. It was designed exclusively for point-blank personal defense encounters, and the rudimentary sights on most 380 pistols make aiming difficult beyond this distance.
The 22 LR retains functional velocity and striking energy much further downrange. Because it is usually fired from a rifle equipped with proper sights or a magnified optic, a shooter can effectively strike small targets out to 100 yards with predictable holdovers.
380 vs 22 LR Accuracy
Accuracy relies on the quality of the firearm, the sight radius, and the consistency of the ammunition. In practical applications, the 22 LR is vastly more accurate than the 380.
In documented independent testing, the 22 LR frequently produces incredibly tight groups at 50 yards due to highly specialized, match-grade rimfire ammunition. Fired from a premium bolt-action rifle, this ammunition can routinely stack five shots into groups measuring under 0.5 inches.
The 380 cartridge is mechanically accurate, but it is almost exclusively chambered in micro-compact pocket pistols like the Ruger LCP or the Smith & Wesson Bodyguard. These tiny handguns feature very short sight radiuses and heavy trigger pulls, making it extremely difficult for a shooter to achieve tight groups beyond 10 yards.
380 vs 22 LR Recoil
Both of these cartridges are celebrated for their exceptionally light recoil, but the firearm platform completely dictates the perceived recoil impulse.
When discharged from a standard 6-pound rifle, a 22 LR produces essentially zero felt recoil. When fired from a full-sized handgun, the 22 LR produces virtually no muzzle flip.
A 380 fired from a tiny 10-ounce to 12-ounce pocket pistol generates significantly more felt recoil than a 22 LR handgun. Because the firearms are so lightweight, the 380 can feel quite snappy and uncomfortable to shoot for extended periods. In a slightly larger, heavier pistol like the Glock 42 or Walther PK380, the recoil becomes incredibly mild and easy to control.
380 vs 22 LR Ammunition Cost
Ammunition cost heavily favors the 22 LR, which remains the most affordable factory ammunition available worldwide. Current retail prices dictate how often a shooter can practice without financial strain.
As of September 2026, representative retail prices indicate:
- Federal AutoMatch 22 LR (40-grain, 325-round bulk box): $19.50 to $26.00 per box, equating to $0.06 to $0.08 per round.
- CCI Standard Velocity 22 LR (40-grain, 50-round box): $4.50 to $6.00 per box, equating to $0.09 to $0.12 per round.
- PMC Bronze 380 ACP (90-grain FMJ, 50-round box): $15.00 to $22.00 per box, equating to $0.30 to $0.44 per round.
- Federal Premium Personal Defense 380 ACP (99-grain HST, 20-round box): $22.00 to $28.00 per box, equating to $1.10 to $1.40 per round.
Practicing with a 380 typically costs four to six times as much per trigger pull as practicing with standard 22 LR ammunition.
380 vs 22 LR For Hunting
The 22 LR is an outstanding small game hunting cartridge. Inside of 50 to 75 yards, a standard 40-grain solid bullet or a 36-grain hollow point will cleanly harvest squirrels, rabbits, and grouse. It is heavily supported by the hunting industry with specialized ammunition.
The 380 is completely unsuitable for hunting. It is manufactured exclusively with self-defense in mind. The tiny handguns chambered in 380 lack the necessary accuracy to safely hunt small game, and the bullet trajectory drops rapidly. Most jurisdictions legally prohibit the use of semi-automatic pistol cartridges for small game hunting.
380 vs 22 LR For Target Shooting
For plinking, skills training, and recreational target shooting, the 22 LR is the undisputed champion. The combination of practically zero recoil, low noise, and incredibly inexpensive ammunition makes it the ideal choice for high-volume range sessions.
The 380 is a poor choice for dedicated target shooting. The ammunition is highly expensive, and firing tiny pocket pistols for extended periods can be physically fatiguing due to their small grips and snappy recoil. A shooter will quickly spend a significant amount of money during a casual afternoon of plinking with a 380 compared to a 22 LR.
380 vs 22 LR For Beginners
For new shooters, the 22 LR stands as the absolute best choice. The complete absence of recoil and the very mild report prevent inexperienced shooters from developing a flinch response. A beginner can dedicate hours to mastering sight alignment, breathing, and trigger control without physical fatigue or heavy financial costs.
The 380 is a poor choice for a beginner’s first firearm. While the cartridge itself is not overly powerful, the micro-compact pocket pistols it is chambered in are notoriously difficult to shoot accurately. The snappy recoil in lightweight frames and heavy double-action triggers will often frustrate a new shooter. The most practical recommendation is to learn the fundamentals strictly on a dedicated 22 LR platform before moving up to a 380 for concealed carry.
380 vs 22 LR Firearms
Firearm manufacturers support the 22 LR with a vast array of platforms. Consumers can select from bolt-action rifles, semi-automatic rifles, lever-action rifles, single-action revolvers, double-action revolvers, and semi-automatic target pistols. The 22 LR market remains massive and universally accessible.
Firearms chambered specifically for the 380 are almost entirely compact and micro-compact semi-automatic pistols designed for concealed carry. Famous examples include the Ruger LCP, the Glock 42, the Sig Sauer P238, and the Smith & Wesson M&P 380 Shield EZ.
Can 380 And 22 LR Use The Same Gun?
No, standard 380 and 22 LR cartridges cannot be safely fired from the same gun chamber. The chamber dimensions specified for each cartridge are completely incompatible.
The 22 LR requires a chamber cut specifically for a narrow rimfire cartridge, utilizing an off-center firing pin. The 380 requires a much wider chamber and a centerfire firing pin. You cannot safely swap these cartridges in the same firearm under any circumstances.
380 vs 22 LR Ammunition Compatibility
Ammunition compatibility is strictly determined by the exact cartridge name stamped on the barrel of the firearm.
- 380 ACP is not interchangeable with 22 LR.
- 22 LR is not interchangeable with 380 ACP.
If a shooter attempts to insert a 380 into a standard 22 LR chamber, the slide will not close because the 380 case is significantly too wide. If a shooter drops a 22 LR into a 380 chamber, it will fit very loosely, and the centerfire firing pin will fail to strike the rimfire primer. Attempting to force incorrect ammunition into a firearm is highly dangerous. Always read the barrel stamping before loading any ammunition.

Manufacturer Data vs Independent Testing
When reviewing 380 ballistics, readers must understand the difference between promotional manufacturer specifications and independent chronograph testing. Ammunition manufacturers typically measure 380 velocity using specialized 4-inch test barrels. However, most consumers fire 380 ammunition from pocket pistols with 2.5-inch or 2.75-inch barrels.
Independent chronograph testing provides a highly realistic baseline for actual field performance. When independent testers fire premium 380 ammunition from a standard pocket pistol, the recorded velocities are frequently 50 to 100 fps slower than the figures printed on the retail box. This velocity loss means that commercial 380 hollow point bullets often fail to reach the required speed to expand reliably in ballistic gel, causing them to act exactly like standard full metal jacket ammunition. When sources provide conflicting figures for pocket pistol cartridges, controlled independent testing through the exact barrel length of the consumer’s chosen firearm represents the most practical data source.
FAQs
What is the main difference between 380 and 22 LR?
The main difference is the ignition system and intended firearm type. The 380 is a centerfire cartridge built for reliable feeding in self-defense pocket pistols. The 22 LR is a rimfire cartridge primarily used in rifles and full-sized handguns for target shooting and small game.
Is 380 more powerful than 22 LR?
When both are fired from short-barreled handguns, the 380 is significantly more powerful because it pushes a bullet that is more than twice as heavy. However, when the 22 LR is fired from a 16-inch rifle barrel, it produces comparable kinetic energy to a 380 pistol.
Which is faster, 380 or 22 LR?
The 22 LR is vastly faster when fired from a rifle, easily exceeding 1,200 feet per second. The 380 typically operates between 900 and 1,000 feet per second from a short pocket pistol barrel.
Can a 380 shoot 22 LR?
No. A 22 LR cartridge requires a specialized rimfire firing pin and a narrower chamber. Firing it in a 380 firearm is impossible and unsafe.
Can a 22 LR shoot 380?
No. A 380 cartridge is too wide to physically fit into a 22 LR chamber.
Are 380 and 22 LR interchangeable?
No. The ammunition is never interchangeable. You must only load the specific ammunition that is stamped on the barrel of your firearm.
Why is 380 so expensive?
The 380 is expensive because it is a centerfire cartridge. It requires a complex brass case and a replaceable primer, whereas the 22 LR is manufactured by the billions using a very cheap rimfire case.
Which is cheaper to shoot?
The 22 LR is vastly cheaper. It generally costs between 6 and 12 cents per round, while the 380 typically costs between 25 and 45 cents per round.
Is 380 good for self-defense?
Yes. While it is considered the minimum acceptable caliber for self-defense by most experts, the 380 offers highly reliable centerfire ignition and allows shooters to carry a firearm that is small enough to conceal in any clothing.
Which is better for beginners?
The 22 LR is the best choice for beginners. The low noise, lack of recoil, and highly affordable ammunition allow a new shooter to practice fundamental marksmanship skills comfortably and frequently before stepping up to a 380.
