What I have found with those land cannons, .460 S&W/.454, they are effective, but come at very big costs!! As you wrote the weight is one cost, next is the recoil that not too many shooters can handle, and many of the revolvers they come in are 5 shots. I've got a Ruger Super Blackhawk Bisley.44 mag that I'm parting ways with because of the recoil and tha smaller grip, and….the weight!! For me it's a fun gun to shoot if it's with mild .44 specials, but it's not a hunting gun or worth carrying in the woods if one cannot hit a barn with it!! I like the security of the G20, there's 16 rounds in the gun that I can manage the recoil on quite easily and it doesn't weigh in at 48+ ounces, and…. I actually enjoy practicing/shooting/training with it. I black bear hunt ground blinds, so for sitting I prefer the Craft, cross-draw holster. I've found the chest holsters to be handy, however the are also noisy when positioning a rifle for a shot. The ground blind is set 40-60 yards from the bait barrel, a bear cannot see too well but it does have some extremely keen hearing!!! Just a slight shuffle in a chair can send one off into the woods never to be seen or heard from again!! Anyways another rambling $.02c worth of my opinions on G20s
