Similar names, different calibers – an essential guide!

Handgun ammunition can be a confusing topic, especially when it comes to comparing different cartridges. In this blog, we will take a closer look at some popular handgun cartridges and the differences between them.


Starting with the 9mm Luger and 9mm Makarov, both are 9mm caliber cartridges, but they are not interchangeable. The 9mm Luger, also known as the 9x19mm, is one of the most widely used handgun cartridges in the world. It is a versatile cartridge that can be used for self-defense, target shooting, and even law enforcement applications.


On the other hand, the 9mm Makarov, also known as the 9x18mm, is a Soviet-era cartridge that is still in use in some parts of the world. It is a less powerful cartridge than the 9mm Luger, but it is still a viable option for self-defense and target shooting.


Moving on to the .45 ACP and .45 GAP, both are .45 caliber cartridges, but they have different case lengths and operate at different pressures. The .45 ACP, also known as the .45 Auto, is a powerful cartridge that is commonly used for self-defense and target shooting. It has a case length of .898 inches and operates at relatively high pressure.


The .45 GAP, on the other hand, stands for Glock Automatic Pistol and was developed by Glock as an alternative to the .45 ACP. The .45 GAP has a shorter case length of .768 inches and operates at a lower pressure than the .45 ACP. Despite its shorter case length, the .45 GAP is still a powerful cartridge that is suitable for self-defense and target shooting.


Finally, we have the .38 S&W and 38 Special. The .38 S&W is an older cartridge that was once popular for law enforcement and self-defense applications. It has a case length of .905 inches and operates at relatively low pressure.


The .38 Special, on the other hand, is a more powerful cartridge that is commonly used for target shooting and self-defense. It has a case length of 1.155 inches and operates at a higher pressure than the .38 S&W.
