I'm 66 and work out regularly; my Winchester 12 gauge SX3 kicks hard with heavy loads. I bought a Beretta 12gauge A400 Extreme Plus yesterday. So my first three shots today were 3" 1 3/4 loads. Guess what? This gun kicks hard; I think this "Kick-off" selling point is overrated. I don't regret buying this gun; it is an elite shotgun. Does it need a break-in period for its recoil system?
