I found this nice leather bandolario field holster online. The only problem is they have discontinued the holster for the GP100 which is the one I need. They still have two of the holsters for the Super Redhawk. My question is, will the GP100 fit in the Super Redhawk holster. I know the holster will be longer at 7.5", but what about the frame & cylinder, Is there that much difference, or will the Super Redhawk holster swallow the GP100? Any advise would greatly be appriciated.
