Nope I got that point. I haven't played RD:Revolver but if he is capable of reacting like with the dead eye meter that is on Redemption, all he has to do is simply un-holster the gun and fire, cause the reaction speed in the dead eye is fast enough to compete here.
It is just a simple pull the barrel out and turn it towards the opponent and fire. Testing a normal human on quick draw it takes about .28 seconds to get a full draw and shot off, about .11 seconds to get the draw I was referring to, and using dead eye which seems to put their reaction at above the human norm I would guess it would half that.
Unless Link and Kratos both can draw and fire bows at .09 seconds or faster they lose.
