bowfiend- it's a Ruger Redhawk 454 Casaul, yep it is heavy. I have been hiking the hillside trails around my house with my pack as training lately. ( 18-20 inches of snow the last few days has not helped) so I strapped the side arm on for extra weight in my pack right now as I have not loaded my food for the trip yet. Everything else is in there, tent, sleeping bag, stove, fuel, pot cup,spork, rain gear, etc. havn't weighed it yet, I am guesssing about 50 pounds without the handgun.
