To the best of my knowledge the 1200,2200 and 1300 are the same shotgun with cosmetic changes to the external areas of the shotguns.All three have rotating bolts.
The 1200 came out first.Then the 2200 came out as the less expensive version of the 1200.Later both 1200 and 2200 were droped from the line and the shotgun with cosmetic changes was introduced as the 1300.
The 2200 was assembled in Canada with hardwood (birch) stocks and forearm.The 1200 and 1300 had walnut stocks and forearms.
