Is there any rimless pistol calibers or calibers in general that can fit into pistols that is more powerful than 10mm whilst being the same diameter or smaller?

I like 10mm, and its a good cartridge. But it would be neat if there was something that was a little skinnier and was still around the same power level if not higher. The only thing that I am aware that fits the bill is 7.5 FK which is also a really cool round. But I have heard issues with it and its still only in one available gun. 30 carbine is a nice contender, a little long but still manageable grip wise, even in a double stack. But it loses a lot of its power in a shorter barrel. Perhaps if it was developed more it could be better in a pistol platform. You have other wildcat cartridges that are similar in size and power like 9x23 dillon but generally offer little benefit if any over 10mm in a normal sized gun. Is there anything available or from the past or something a little unorthodox that fits this bill?
