To follow up on my post 39, I think Glock, H&P, and XD are all offering slim single stack models these days, so you can probably find something as compact as your .380 in a larger caliber without any difficulty.
Sig makes a 9mm P938 that is essentially the P238 in a larger caliber, very small increase in size.
However, I can’t comment as to how good it is, only having personal experience with the P238.
