Nothing, from Canada to LA, has been as dead nuts reliable for me on waterfowl, in all conditions, as a Browning Auto 5, period. I’ve owned Benelli SBEs, M1s, Beretta 390/391 and others, Remingtons, and more. I’ve had to fix or fiddle with all of them to keep them running...mine and those of others in the blind, enough times that I generally stay with one of my Mag 12 stalkers. If I was hiking miles for pheasant, grouse, chukar.....general upland, there’s lighter choices. Even then, a SW16 ain’t half bad, and a Superlight 20ga Auto 5 was maybe the perfect quail gun. Regardless, none of the other types have the moving mass to defeat the crap thrown at a waterfowl gun, without at least constant maintenance. If you care for them daily, most will run fine unless the ice/grit/stubble/mud monkeys show up.....gas/inertia....doesn’t matter. Horses for courses and all that. JME.
