Anything that fits an Officers ACP should fit the Combat Master, as long as the top/front doesn't interfere with the rear sight. I ordered a holster from FIST, and they made a custom version of an OACP design, with a low-cut front to clear the sight. I use that holster, of the "Avenger"/Vertical Scabbard/55BN style for competition, and use a Galco Jackass and Uncle Mike's fanny pack for carry.
