Have you looked at the Kahr CW9. It meets all of your requirements. You can find them new for $400-$425. They weigh right around a pound and you can go to Kahr.com and view the leather ankle holster they have. They are only slightly larger than the PM9 but I think easier to shoot. They are identical to the more expensive P9 except the slide is not machined as fancy (same material though), they use standard rifling barrels instead of polygonial rifling and the slide release is MIM instead of CNC. You can go to Kahr.com to see them compared to other Kahrs. I have one and love it. I think it is the best subcompact in that price range.
