Good choice on brand. Benelli shotguns are the best.
As far as tips, what are you doing with the shotgun? Home defence, 3 gun, ranch gun, etc.
The tips I have:
Take apart the gun and clean it well and get to know your new shotgun.
Get a limbsavers pad
Take it to the patterning board
Enjoy your new toy
Good luck and have fun!
