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.
From a single billet at Mizuno’s exclusive facility – where Mizuno irons have been produced since 1968.
A microlayer of copper beneath Nickel Chrome – an additional touch to enhance the sensational feel of our Grain Flow Forged heads.
Applied to closely match the vibration patterns identified with a soft muscle-back feel.
Solid feel and control where most needed, with modern lofts to maintain even distance gapping through the set.
A wider, longer micro-slot to create a more expansive high energy area of clubface – resulting in a higher flight and faster ball speeds.
Increased by a degree in the long irons and 2 degrees in the scoring irons – for improved turf interaction.
Heavy relief around the sole for improved turf interaction and seamless transition from micro slot 7 iron into traditional 8 iron construction.
Dramatically reduced topline and blade length throughout the set.
A less reflective, modern finish.

*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).
