I owned an Italian-made replica of a Walker Colt at one time. It was huge and weighed a ton.
Only felt like it weighed a ton. . . 9 ½ pounds loaded. Fun to shoot. Tongue of flame for fifteen feet from the muzzle! WHEEEEE!
I own a few myself. Very fun to shoot. If anyone is interested, here is the catalog -
