Home Forums Birds & Dogs Shotguns Difference between the Winchester 140 and 1400?

Not an expert but as I remember it, the early model semi-auto (introduced around 1964) was the M1400. Later it was updated with some visual and mechanical changes and became the M1400 Mark II (not sure what the changes were). Later still it evolved into the M1500XTR for the higher grade and the M140 for the cheaper grade.
