I have some friends with them. Very reliable with heavy 2 3/4" loads, 3" loads, and 3 1/2" loads. Less reliable if you want to shoot light 7/8 or 1 oz loads.

Unless you need to fire 3.5"shells the M2 is a more reliable trouble free shotgun overall.

This is my experience, I have no need for 3 1/2" shells, but will shoot a lot of lighter loads for clays games. I have the older M1, but if buying new today the M2 is a better fit for me.

But if you want to shoot long range geese with steel shot the 3 1/2" shells make sense.

Most people don't really want the truth.

They just want constant reassurance that what they believe is the truth.
