A 9mm carbine is a semi-automatic or fully-automatic firearm that uses 9mm Luger ammunition. It is typically larger than a pistol but smaller than a rifle, and is often used for self-defense, law enforcement, and military purposes. The 9mm carbine is a popular choice for these applications due to its relatively low cost, ease of use, and compact size.
There are many different 9mm carbines on the market, each with its own unique features and benefits. Some of the most popular models include the AR-9, the CZ Scorpion Evo 3, and the Kel-Tec SUB-2000. These carbines offer a variety of features, such as adjustable stocks, Picatinny rails for mounting accessories, and different barrel lengths. This allows users to customize their carbine to meet their specific needs.
