Quality shotguns are made by companies that have names that end in vowels!
In most all cases Field guns and Comp guns are exactly the same! The main difference is in the features and fit.
Funny how we get all spun up about tactical guns and their quality when they spend most of their life "racked" in some room or in the cruiser and see very little range time.
Good gas guns rock! If you put shit in (ammo) you get shit out!
I would have no problem taking a tested and proven duck or dove shotgun to a fight especially over one that was labeled tactical.
A pump shotgun offers NO advantage in the field over a gas gun.
