For pure ugly durability Benelli!!!
Have used an M2 at work for 22 years, around 30k rounds.
The only thing that failed was the pin that holds the magazine catch.
Every other failure has been operator failure, there is a learning curve
to keep them operating at below zero degrees.
22 years and 30K interesting. I think I had 30K in about two years. Three M1's, one with over 100K and the other two are both north of 30K.
The M1's have no equal!
Can't speak for the M2 have never owned one, but the M1 runs fine in below zero without the need to learn to keep them operating. Have hunted Sea Ducks in Alaska, Connecticut, Maine, Massachusetts, New Hampshire, New York, and Rhode Island. Divers and Puddlers in Alabama, Arkansas, Mississippi, Montana, Tennessee, Texas, and Vermont. The gun has operated fine in all conditions. So it has seen plenty of very cold days.
