I think I've found a holster that will work...are drop leg holsters kosher? I didn't see anywhere in the rules one way or the other?
My biggest problem is that, being a luddite, I don't own any pistols with built in rails for the lights, so I had to get an adapter. But holsters made for lights usually assume that the pistol has built in rails. The adapter throws the dimensions off, and things don't fit.
Yeah, and M&P Pro is on my shopping list, but that's way down the road.
