I had a Preban Benelli M1 tactical.
I will say that you can't match if for pure speed in chuck'in shells out. Recoil can be miserable with the full power loads like Winchester Double XX 3" with copperplated buckshot. (otherwise know as Supreme brand).
Some Benelli's can be picky when they are new, especially with the light loads like your basic rabbit and squirrel offerings. Sometimes these loads don't have enough to them to cycle the system all the time. For a combat shotgun go with the pistolgrip it will assist in one hand firing and controlling recoil with the most powerful loadings. If you aren't lucky enough to acquire an original Benelli with the one piece mag tube. A two piece will suffice, but overall capacity will be deminished when loading with certain shells. I got 7 rounds in my benelli when using rabbit and squirrel loads, and 6 when I used double xx 3" buckshot.
The tactical is a nice setup, slightly shorter barrel as compared to original and your choice of three choke tubes. Buy a Benelli, it's the true master blaster.
