Baikal, bounty hunter
The Russian import guns, from Baikal, are serviceable doubles. The short SXS guns made for the cowboy crowd were/are marked "bounty hunter".
I'd stay away from external hammers unless you work with them a great deal, or are familiar to start. Most of us are accustomed to snicking off a safety as in the hammerless models.
The 311 is a great gun, but I'm not sure about factory 18" bbls. That sounds "sawed off" to me. At the risk of sounding commie-lib, I would not want to defend that in a civil/criminal setting. Maybe it is factory and I'm wrong. A gun that has not been modified, but is stock in its makeup, would be more defensible. Simply put, I would avoid a double that has been "sawed off" as a HD gun.
If I could find a 311, 12 ga, 3" full and full, possibly full/mod, 28", at less than an arm and a leg in cost, I'd have a new turkey gun!. .....$250, what a steal!
