Im not understanding.........nothing happens more or less than it would with any gun...
The recoil reduction is on a whole, the whole gun will actually slide back an inch backwards over the handle when firing as the cam lever is in the handle on the copstock. I suppose if your a glutton for punishment and you somehow get your face that close to the back of the gun youre in for some bloody good times. Im SURE some lucky fellow without a clue has done this haha. It happnes so quickly you wouldnt even notice this though.
However, I dont see how your hand or trigger finger is affected in any way, nor have i had it effect me.
