Marlin Camp 9 (9mm) or Camp 45 (45 ACP) are pistol caliber carbines. Ruger PC9 (9mm) or PC4 (40 S&W) are too. A 30 carbine arguably is considered by many a pistol caliber carbine also. Let's not confuse pistol caliber
; they are two different animals.
An AR-15 is pistol gripped, but most wouldn't consider the 223 to be a pistol caliber. Platform style and platform caliber are two different considerations.
