I have a sbe1 and a xtrema 2 without the ko.I can say that my benelli is not the most reliable gun out of the two, yet for some reason the recoil is less than that of its sister the xtrema 2.I was shooting 42 gram mini mags out of it and would have to say the benelli acutually felt nicer to shoot.Remembering that the xtrema i have does not have the kick off.I think too many young shooters focus on the recoil of the gun not the actual qualities they bring.Recoil should not be your greatest concern when buying a gun, the fit of the gun is more important.And you say you are 15 so Youll grow to exccept recoil.Its part of shooting.Either way you can't go wrong.Yet i personally think that the xtrema is a better gun.Yet youll have to decide what you want out of it.I think youd be better off buying second hand untill you get more confident with a shotgun.
