Pistol caliber carbines are all but dead in any caliber. The advent of carbines built on the AR platform have replaced them. Cheaper to build quality guns, use the same ammo and larger capacity magazines as full size rifles, same basic size and weight as a pistol caliber carbine, less chance of over penetration when compared to pistol rounds, and much more effective perfomance.
The only pistol calibers that serve any useful role are the ones chambered in calibers like 357, 44 mag etc. that can use heavy bullets and be effective for deer, back bear size hunting.
