Well I am diving in head first with 3 gun. My shotgun came in today that I will be using. Its a Versa Max Tactical with 22" barrel and 8+1. I am a newbie to 3 gun competitions and I know this gun was made to be an out of the box competition gun but does anyone have any reccomendations on setups or mods I should do before my first competition. Does anybody have any experience using these at competitions?
