Have three of them. My 1963 light twenty was my weapon of choice on a Kansas pheasant hunt a few years ago. Easy to carry, shells are lighter, and I killed as many or more ringnecks as anyone else. Oh, and it's a 26" improved cyl. with a vent rib.
You will not be sorry.
I think I have read that the A5 was one of JMB proudest accomplishments. And he had plenty.
