For concealed carry:
Ryan makes them for all sizes of P250s.
I have a nylon holster that will hold a P250 of any size and it has a mag pouch as part of the holster. It will hold a P226 or a P229 with a laser on the rail. I just can't think of where I got it from. It is good enough for the range or just walking the woods. I would never consider it a concealed carry holster.
