From Milt Sparks? It might fit it "ok" but it won't be nearly as nice as a bespoke holster for the BHP. You can just call Milt Sparks and order one; I think their wait time is around 3 months now. Which sounds like a lot, but just like NFA...you place your order, forget about it, magic happens, and then it shows up in your mailbox. I sprung for a Summer Special II for my BHP a couple of years ago and I'm very happy with it.
I'm sure the kydex clips on Top Gun Supply can be used on other similar holsters as well, at least ones where the belt loops are removable...I'd personally stick with Milt Sparks for leather, but there's quite a few leather makers out there that are really good as well, so there's no need to lock yourself down if you don't want to be.
