Mizuno MP-20 MMC
Our take: Mizuno has proven with the MP-20 MMC irons that even difficult things can be accomplished when done with precision design and top-notch engineering. According to one our testers, these irons “feel amazing, even when shots are hit away from the center of the clubface. Can’t remember using an iron with a compact shape that was so forgiving and had such a flushed sensation — on good hits and even on some that were less than perfect.”

Mizuno MP-20 MMC Irons
The details: The MP-20 MMC irons are Grain Flow Forged from a single billet of 1025E mild carbon steel, but also come with strategically placed titanium in the muscle and a tungsten sole weight—for added feel, sound, and a higher launch with an elevated MOI. A copper underlay (beneath the outer shell) further softens the feel at impact, resulting in one of Mizuno’s most playable-yet-versatile irons to date.
