Thanks for the response, vandy.
I want a closed-muzzle holster (to keep lint out of the barrel), so the "grip" won't do.
As far as I have been able to ascertain, Hedley does not make a holster for the Mini-Master.
I have ordered the suede open-muzzle belt holster offered by NAA. Perhaps I can get my cobbler neighbor to sew the open-muzzle shut for pocket carry.
