Here is a link to a list of holsters that fit the P250. I too am trying to decide which holster to start with for my
new P250. Maybe some of these will be good choices for you.

How do you like your P250? how many rounds have you fired, and how did it perform?
I have about 75 rounds through mine and so far I really like it. I am going to try to get out to the range again next weekend and put another box or two through it.
Good luck in your holster search.
