I recently bought a Falco (marketed in the US by Craft Holsters) belt holster for my Super Redhawk 454 Casull. The holster was built so as to accommodate a red dot sight. Quite impressed with the quality of the workmanship but not to sure whether the leather is heavy enough for long term use with a heavy revolver. Time will tell. (would be perfect for your typical CCW type auto). I'm not too fussed by this as I only needed the holster as a 'range bucket' ie something to carry the gun in while at the range so as to avoid leaving the gun on the bench when checking targets etc.
I have been considering their Roto style shoulder holster as a hunting holster for the SRH. Again I suspect the leather thickness may have been designed around lightweight CCW autos. Wondering whether anyone has had experience with them for hunting use with a heavy revolver?
