Confused about the "Carbine" category

The PX4 does have a 'de-sporterized' SMG variant now (MX4). We'll probably see some in films eventually, since they're so 'futuristic looking'. Classifying it is sort of the same situation as the HK94, but backwards.
The DeLisle was based on a SMLE, so I'd call it a rifle. Even if it fires .45ACP from a 1911 mag through a Tommy gun barrel.

You forgot to mention the Lee-Enfield stock. EDIT: oh, wait you did. Never mind

So we'll put the MX4 on the same page as the CX4 when it starts appearing in media, much like we have pistol-caliber carbines on the same pages as their parent firearms (such as the Uzi SMG and Uzi Carbine, the MP5 and HK94, and the UMP and UCP)?

It seems pretty rare that an SMG version of a pistol-caliber carbine is officially produced after the pistol caliber carbine is commercially available.
