No
The only barrels that will fit the Winchester model 120 are all model 1300 winchester barrels,and most model1200 Winchester barrels.So the answer to your question is No.
I recently called the Winchester historian and he said they were the same gun also a model 1200 barrel will fit.
No
At this time no,there are not any available.You could have a model 1300 slug barrel redone and have the gas ports added to this barrel.Then it will work fine in your model 1400 Winchester shotgun.
No
Not too sure but I do know a Sears Model 300 barrel (their clone of the 1400) will not fit a 1400 action.
yes
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
No
NoThis is from the Winchester Website:How versatile are the Model 1300 barrels? Will they fit earlier or different models?The Model 1300 barrels will fit Model 1200 receivers, but 1200 barrels will not fit a Model 1300. Model 1400 barrels will not interchange with Models 1200 or 1300 barrels.The Model 1300 Defender barrels will not interchange with the 1300 Field models and viceversa.
