I do not own any of these biguns, but this reasoning is so sound that I would not ignore it.

I had a 4 lb 12 bore once. It was a 19 inch bbl'd H&R singleshot and though I quit boxing years ago occaisionally I felt like feeling something from the good ole days {getting beatup} so I'd shoo the horses out of the front pasture and take it out on the front yard and run a few rounds of 3-inch mag 00 thru it at chunks of firewood and the like.

I'm not a big guy, but I assure you that this thing would have made Mike Tyson consider the priesthood and had it been a double and I was shooting it, the left barrel could have been left unloaded and probably reloaded faster with a round from the back pocket of my jeans than I could have gotten the spare trigger yanked.

Those that know tell me a .577 is a real He-Man's gun and might very well make my 12 bore lightweight feel like a peck on the cheek from Gramma.

Making a "fightin' gun" fit for a pussy isn't a copout, it's good common sense.

My vote would go for a heavier {though not necessarily LONGER-barreled} gun. I like stubby guns.

Go ahead and make it short if you like, but make it heavy, too.

Just $.02 from a guy who knows enough to get out of the way of a mean bull or a guy bigger than me, but not much more...
