My Browning 12 has 30 inch barrels and goes about 7.5 lb. I’ve lugged it many miles for pheasants and ducks. It’s killed more birds than Colonel Sanders but is really too heavy for a true upland gun.

Lighter guns from Browning, Ithaca/SKB and Ugartechea (as Ed pointed out), are often found well below $2000 and can be good choices. As long as you don’t overpay, and give them reasonable care, they will hold their value forever.

True vintage guns, as battue suggests, are a bit of a risk until you know exactly what to look for. In almost all of these, small gauge guns have skyrocketed in price. Some nice 12’s can occasionally be found at reasonable prices. My most carried gun is a 1930’s Ithaca NID 12. These are solid guns and can sometimes be found at bargain prices.

BTW, I only buy guns that fit me, or can easily be made to do so. I also am quick to have chokes opened if it fits my purposes. I am a shooter, not a collector. I’d sooner hit with a Mossberg than miss with a Parker.
