The M1 carbine rd is not considered a pistol caliber.

Several handguns have been chambered for .30 carbine over the years. But I get your point.

What is a pistol caliber these days?

They have chambered pistols in 460 Weatherby.

I have had a Contender pistol in 357 Herrett for many years. It is a shortened and blown out 30-30.

I now have its bigger brother, the 358 Yeti, chambered for the AR-15. It is a shortened and blown out .308.

I also had a 256 Ferrett Carbine. It used a 357 Magnum case necked down to 25 Cal and shot out of a modified M1 Carbine. Also known as the 256 Win Mag.
