Check out Simply Rugged's pancake holster with the Chesty Puller rig. I use it for my 4" Ruger SRH and will also be using a similar setup for my 625 Mountain Gun.

Pancake holster has the flexibility to wear strong side and crossdraw. Add their inside the waist band straps and you can wear it as a IWB holster.

Flexibility is excellent and turnaround is 4-6 weeks.
