most people will say they are the same. I have both a 1200 and 1300 and have fiddled around with both to see which parts are the same and which arent. When i switched the trigger assembly they didnt fit quite right. i felt that i had to jam it in a bit much. when it was in it cycled fine. i switched bolts at the same time and when i racked the action the bolt felt like it was grinding on the reciever.
