Everything but 9mm is a dead pistol caliber realistically. That's why many guns (pistols or pcc) are only or mostly released in 9mm. And to be fair it makes sense. If you need more than that there is .223
I finally got my PC9 out shooting. It ran 100% flawlessly with a variety of FMJ in 115 and 124gr loadings. Plinking steel targets at 150y and beyond is a hoot. Very easy pointing and smooth running gun!
Do you have a scope or red dot on yours? I am trying to figure out what works best on these, especially with my aging eyes.

So would I. I'm hoping for a .44 mag sometime in the near future. In that chambering this carbine would be more practical for my use.I would hunt with a pcc in 44mag,
There is no way Ruger is releasing a .44 PC carbine. It would require a complete redesign of the rifle. That should be obvious to anyone with even a basic understanding of the PC and/or blowback gun engineering. I could see the rifle as currently offered handling 10mm Auto at most before serious re-engineering would be necessary.
If it won't take 44 it won't put up with 10mm other than factory loads that are basically a 40cal.
The 10mm could fit, that's the biggest difference... Have you even held a PC carbine? It really surprises and sort of confuses me that you are so confident it would work.
