I recently called the Winchester historian and he said they were the same gun also a model 1200 barrel will fit.
yes
No, a Model 1400 Winchester barrel will not fit on a Model 1200 Winchester. The two models have different designs and specifications, including variations in the action and barrel attachment system. Always ensure compatibility when considering parts interchangeability between different firearm models.
To answer your question, If you pay attention to some of the specs on the model 1300 barrels some of then fit the 1200 model. Just make sure when shopping for the 1300 model barrel that it says it will fit the 1200 model or you are gonna blow your money for nothing
Not too sure but I do know a Sears Model 300 barrel (their clone of the 1400) will not fit a 1400 action.
