You might want to check out leather holster's from
Bianchi and Safariland, as they offer several model's.
Both, are high quality state-of-the-art leather maker's.
I have a DeSantis Style 08 Swivel Shoulder Rig for my 6.5 inch 629 DX. Gun is seated vertically but the swivel allows for horizontal draw. Really like the way it works. Check it out at www.desantisholster.com
