I have watched a lot of Beretta 1301's in a lot of shotgun classes. They run. They are also less expensive, if that is a consideration.

They cycle faster, and seem to be less ammo-sensitive than the M4's I have watched. They are lighter, and I really like the balance better on the 1301 as well.

I own a Benelli M2, which pretty much just sits in the safe. The 1301 gets run, a lot, and run hard. I just add lube and ammo.

I supposed some day I should clean it.......
