The 1200, 1300 and 1400(which is a semi) all ultilize the identical receiver, with the 1300 having a slightly longer ejection port to accomodate the 3 inch shells the 1300 was designed for. Obviously the 1400 will have some slighly different machine cuts inside the receiver, but the outside is the same. So the answer is yes, it will fit your gun. Additionally, the 20 gauge of all 3 of the above persuasions are built on the same 12 gauge size receiver, so stocks are actually interchangeable between all 3 models mentioned and 12/20 gauge.
