I don’t really consider any rimfire cartridge carbines to be PCCs but I suppose they technically fit the definition.
I suppose lever guns invented the concept way back when and I have an 1894 in 44 mag. It is a fun gun to shoot. I also have a PCR….a pistol caliber rifle. A Browning 1885 in 454 Casull.
I am less impressed with PCCs in smaller pistol cartridges like 9mm or 357 though. I don’t see them as any more fun than shooting those cartridges in a handgun. 44, or 454 can be a pretty stout handgun round that can fatigue you quickly but are much more manageable in long gun form. For 9mm, 40, 45, 10mm, and 357, any argument folks make for them being “fun” I will just counter with the handgun being fun too. I suppose if it’s just another excuse to buy another gun though….
