You're probably asking about what's called a pistol caliber carbine. Those are short rifles chambered for a pistol caliber bullet, e.g., 9 mm, 45 ACP, 40 S&W. Guns that fall into this category includes the Ruger PC-9 & PC-40, the Calico 950, Uzi Carbine (16"bbl), HK-94, Colt AR-15 in 9mm, etc.
Note: The "term" carbine has evolved over the centuries. Back in the days when a long barrel gun (39-46" bbl) was cut down to 33" or so, the shorter barrel gun was called a carbine. During the Civil War, rifled muskets were around 39" long, short rifles 33" or so, and musketoons a mere 24" long. See how it changes? The German Mauser 98 of WW I fame featured a 29" long barrel. The Mountain Carbine version was a mere 24" long. Modernly many of our commercial rifles are 22-24" long. So, when you apply the term, also consider the period in which it is being used.
