The Mizuno Pro 243 is a manufacturing masterpiece – more compact and precise than its predecessor, yet faster from the face and more satisfying at impact.
Improvements in performance only made possible through the long-term relationship between Mizuno’s R&D team and its exclusive Grain Flow Forging plant in Hiroshima, Japan.

*Mizuno will soon be changing its official iron measurement method to match the USGA / R&A standard. As a consequence our published USGA/R&A club lengths are now approximately 1/4 inch longer (when actual club length is unchanged).
