Welcome! I agree, you might include some more parameters here. You’re going to get a ton of recommendations all over the map.

By a .22lr pistol and plenty of ammo. It makes range trips less painful to the wallet.

Welcome to the forum.

A larger conceal carry, you say? How do you feel about your current P320SC? What is it about that one that has you yearning for something else? You are correct in saying that there are A LOT of options out in the wild. But without further guidance from you, we're just taking stabs in the dark.

As for what I would buy for myself as your question posed: well I'm a Glock guy and have been for over 3 decades, so for a CCW it's kind of a no brainer for me if I'm looking for a larger carry weapon than your P320SC. I carry a .40 G23, so that would be my choice, albeit in Gen4 and not the current Gen5 with its girthy slide to compensate for the lost frame pin. As for 9mm, it would be the G19. Not sure if that's really any help in your situation, but those are my answers.
