While the previous M2 was a fine golf club, the new M4 blows by it with numerous improvements, including a high-MOI head design that improves stability by 24 percent. The RIBCOR design, which—along with a variety of other technologies, including TaylorMade’s Inverted Cone—stiffens the outer frame and increases the transfer of energy to the ball at impact, yielding massive ball speed and distance that can benefit just about any type of player. RIBCOR also dampens vibrations at impact, greatly improving sound and feel over the previous M2 model.


“A forgiving, high-launching iron that will give anything in its class a run for its money. Fast off the face, with plenty of mid-spin forgiveness, this is an iron that should be friendly to higher-handicaps or anyone who wants to hit it longer.”
