Extra cylinder for Ruger 357 Blackhawk
One of the guns I inherited from my grandfather years ago is a Ruger Blackhawk .357. It appears to have never been fired and new in the box. (Since it was 'NIB' I just kept it that way but I'll probably shoot it soon.) Anyway, included with it is a spare cylinder that appears identical to the one in the gun and I'm not sure what it's for, other than to have a spare cylinder. And it's not like it's a quick-change Clint Eastwood style, as you have to depress a spring loaded button with one hand to withdraw the rod with the other to remove the cylinder. So, what's the spare cylinder for? Just to have a spare?
