I've got 2 white hat holsters I use for my M&P's IWB. I haven't tried their OWB holsters but they'd probably function as well as most of the other brands in the same price range. Kinda funny looking though.
For my revolver I went with a sourdough pancake holster. Which is strictly a revolver holster but id recommend the brand. I've also got a des santis facilitator that I can't say is very good.
I'd definitely try White hat
