The 9mm Kurz and .380 are two popular handgun cartridges that have been around for decades. These cartridges have unique advantages and disadvantages, making them suitable for different kinds of shooters.
They are both famous for concealed carry, home defense, and target shooting. The 9mm Kurz is a shorter version of the 9mm Luger, while the .380 is a slightly smaller caliber than the 9mm.
Both cartridges offer good stopping power and accuracy, but the 9mm Kurz has more suitable penetration, and the .380 has less felt recoil. This article will compare the 9mm Kurz and .380 and discuss their strengths and weaknesses.
At A Glance Of 9mm Kurz & 380
The 9mm Kurz (also known as the 9x17mm) and the 380 ACP (also known as the 9x17mm) are two popular handgun cartridges.
Both are small and light and have been employed for self-defense and target shooting. The 9mm Kurz is a smaller version of the standard 9mm Luger, while the 380 ACP is slightly larger than the 9mm Kurz. Both cartridges are effective at self-defense, but the 9mm Kurz has a higher muzzle velocity and is more widely available.
The 380 ACP is slightly cheaper and has less recoil, making shooting easier. Both cartridges are popular among shooters, but the 9mm Kurz is generally considered the better self-defense choice.
9mm Kurz Vs .380 ACP – Key Differences
History
The 9mm Kurz and the .380 ACP cartridges were produced in the early 1900s. It was developed by the German weapons manufacturer Mauser in 1902 and was designed as a shorter version of the 9mm Parabellum cartridge.
The .380 ACP was developed by John Moses Browning in 1908 and was designed as a smaller version of the .45 ACP cartridge. It was initially intended for use in the Mauser C96 semi-automatic pistol and used in various submachine guns.
The German military widely used it during World War I and World War II, and the police forces of several European countries also used it. The .380 ACP was designed for use in the Colt Model 1908 semi-automatic pistol and used in various other handguns.
The United States military widely used it during World War I and World War II, and was also used by the police forces of several countries.
Today, the 9mm Kurz and .380 ACP cartridges are famous for self-defense handguns. It is a more powerful cartridge than the .380 ACP, but the .380 ACP is more compact and easier to conceal.
Accuracy
The accuracy of the 9mm Kurz and .380 ACP cartridges is comparable due to their similar ballistics and bullet diameters. Accuracy factors include firearm quality, ammunition consistency, bullet design, and shooter skill.
Both cartridges are designed for self-defense at close ranges, where hitting vital areas is crucial. To enhance accuracy, focus on using well-made firearms, practicing regularly, and selecting quality ammunition.
Cartridge Sizes
The 9mm Kurz and the .380 ACP are two popular handgun cartridges. Both cartridges are relatively small and designed for use in small handguns. 9mm Kurz is a shorter version of the 9mm Luger, while the .380 ACP is a slightly larger version of the .32 ACP.
It is a shorter cartridge than the .380 ACP, measuring 16mm long compared to the .380 ACP’s 19mm length. It has a bullet diameter of 9mm, while the .380 ACP has a diameter of .355 inches. This muzzle velocity is 1,100 feet per second, with a muzzle energy of 320 pounds.
The .380 ACP has a muzzle speed of 950 feet per second and a muzzle power of 200 foot-pounds. It has a higher muzzle velocity and power than the .380 ACP, making it a better choice for self-defense. However, the .380 ACP is still a viable self-defense cartridge and is popular due to its smaller size and lower recoil.
Ballistics
Ballistics refers to the science of the movement of shots, such as bullets. There are several factors to consider when comparing the 9mm Kurz and the 380 Auto. It has a higher muzzle velocity and is a larger caliber than the 380 Auto, meaning it has more energy and an excellent effective range.
It also has a flatter trajectory, making it more accurate over longer distances. However, the 380 Auto has a higher magazine capacity and is generally more compact, making it easier to conceal. Eventually, the two preferences will depend on the shooter’s specific needs.
Ammunition Availability
The availability of ammunition for 9mm Kurz and .380 is one of the most important considerations when choosing a handgun.
It is more widely available than the .380, with a wide variety of ammunition available in full metal jackets and hollow point options. .380 is also widely known, but the selection of ammunition types is more limited. Ammunition for both calibers is typically easy to find in most gun stores and online retailers.
