Ok guys, I've read and even posted some thoughts in the 1301 thread. I think I understand the platforms and pros/cons. I've had multiple M1's and really like them. I still have an un-used full set of chokes for an M1. I sold my last 21" M1a couple months back to cover cash flow during a job transition. Ready to get back into a shotgun now and stuck. It may come down to availability. Finding a clean used 21" M1 is proving difficult. A new 21" M2 is available on Gunbroker for about $1,200. A new 21" 1301 is $950. I'm gonna have to buy new chokes with either.
Reasons you can think of to go M2 over 1301?
