Have Rob Leahy make up a holster with his Chesty Puller rig. When I hunt with a handgun I usually use a TC Contender with a sling to carry it but I always have a large bore revolver and I am converted to good leather such as the Simply Rugged pancake.

You can get a holster to fit the DW with a scope and a Chesty Puller rig to wear across your chest.
