Holster ? Recommendations ?

I will be picking up my New VP9sk next week and would like to get a OWB holster for it. I will be using it as my edc but don’t care for the iwb holster’s. I have been looking at the H&K website but not sure which one to buy ? All input appreciated 👍. PS; I’m also ordering extra magazines. Which ones 12 rounds with the pinky or the 15 round magazines ? TIA
