Good idea, I would do the same if I was thinking about buying it.
Maybe you could get him to sent you or post a better picture of the cylinder/lock area.
I showed it to a buddy and he says any handgun with that long of a barrel is a rifle.
I thought that was funny. It sure should not kick with that kind of weight of the barrel. I would love to shoot one to compare it to my Dan Wesson with it's 6" barrel and less weight.
