Holster for 657 (7-1/2" bbl)

[eagle24]

I've been online looking for a good quality leather belt holster for my S&W 657. I can't seem to find one that will accomodate the 7-1/2" bbl. Could someone give me a suggestion of a model of dealer to try. I looked on the bianchi website and also the mitch rosen website and did'nt find one.
