9mm rifles, often referred to as 9mm carbines, are firearms chambered for the 9mm Parabellum cartridge, a popular handgun round known for its manageable recoil, affordability, and widespread availability. These rifles offer the advantage of using the same ammunition as many standard pistols, making them a cost-effective and convenient choice for shooters who already use 9mm handguns. 9mm rifles are appreciated for their lightweight, compact design, and ease of handling, which makes them suitable for a variety of uses, including home defense, plinking, and competitive shooting.
