What are the requirements ?
SxS, O/U, semi-auto ? pump ?
for a pump gun this is my recommendation, other folks will give you theirs....
really nice Ithaca 37 16ga guns are available. that is what I hunt with. one main consideration is pre or post serial nbr 855,000.
pre- the barrels are individually fitted to the gun
post- the barrels are interchangeable
pre- up to about 1954/55 the stocks were more graceful, then there was a change.
regardless, pre-855,000 guns are light and easy to carry and handle like a dream, they all have fixed chokes. most came with 28" barrels, but you can find 26's occassionally
post- start to get heavier and when the transition to choke tubes happened they got a little heavier yet
HOWEVER I own and hunt with both pre and post and either are great guns
