Question: what is the difference between taylormade m2 and m3 irons?
Answer: While the M1 was smaller and more compact than the M2 irons, the M3 has been made even thinner on the sole and the top line. ... Like the M4, the M3 irons have re-designed the Speed Pocket on the sole to a more curved line as opposed to the almost dumbbell shape of the M1.
