I recently acquired a 4" Colt Diamondback and am looking for a concealed carry type holster for it. It seems that nobody stocks these anymore. Even my go-to custom leather guy doesn't have a form/dummy to make one. I've placed ads in the WTB sections on several forums with no luck. I really can't afford the top end custom makers, nor do I want to wait months for one to be made. Anybody know of a source? I've heard that a holster for the Ruger SP101 will fit. Can anybody confirm or deny this?
