I hunted deer for several years, successfully, with my Model 29 Smith with an 8 3/8" barrel in good weather and my Ruger Redhawk with 7.5" barrel. They both have two powered scopes on them. I used a Bianchi Hush System holster (accross the chest) rig in rough country without issue. I can recommend it without reservation. It is quickly adjustable for heavy or light clothing and with the optional flap offers full protection.
FWIW,
