We have two of them that we use in Cowboy Action Shooting. I do not know what the cylinder is on it, but it shoots those steel bad guys at impressive distances. Never thought about modern mountings for it, but my wife's 20 gauge is always with us in the little motorhome. Good mobile home protection device, along with a Glock 23 and a Para Carry9.
