Bought the 12-07. Took her out with a large variety of lowbrass birdshot(cheapest 3 brands that walmart had of 7.5shot), along with multiple varieties of shots and 2 3/4inch buckshot and slugs as well as various 3inch magnum buckshot and slugs. Shotgun flawlessly cycled everything I had and was able to hit my targets with various slugs at 200yds. Im running 5 and 8 round mags(in CO we have mag restrictions which is total BS). As soon as I travel out of state I will be getting some larger mags as well. I added the railed RPK front grip for flashlight, which is sold here at KVAR(recommend). THIS IS THE FINEST SHOTGUN I'VE EVER OWNED. Am now selling my benelli m1. Cheers
