Adding weight will certainly help make the light little gun feel like you're shooting the heavier 12 ga. The problem is muscle memory, for lack of a better term. When we shoot an eight or nine pound gun a lot, as we do during the off season shooting clay games, then going to the lighter gun, it "waves around" and won't seem to settle down on the bird without great effort and wasted time. I truly believe it all can be overcome by shooting the little gun enough for "muscle memory" to imprint with the light gun. Works for me. Anyway, what's wrong with shooting a lot?

May God bless America and those who defend her.
