Any 1911 holster will hold a BHP very nicely.....especially if it is a .40 All manufacturers offer a version of what you are seeking.

If cost is no object a Milt Sparks VM-2 might be a great choice or one of my Favorites for the herd is a Kramer #3.

PS.
Be sure to use a very sturdy belt as well....if you can fold it in half vertically it is NOT sturdy enough.
