M4 is not on the list 'cause it's just too much $$$$$
Primarily for home defense, but I want to do some trap/skeet, and maybe some hunting down the road.
I kind of like the fact you can manually eject a round out of the M3 if it doesn't cycle, but how often do you really need to do that if you're not shooting special LE non-lethal loads? Do M1's cycle reliably with a variety of loads, or do you have to use 00 buck?
