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.

4120 Chromoly with Flow Microslot (4-7 iron)

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 bounce angle

Increased by a degree in the long irons and 2 degrees in the scoring irons – for improved turf interaction.

Wrap Around Sole Grind

Heavy relief around the sole for improved turf interaction and seamless transition from micro slot 7 iron into traditional 8 iron construction.

Exceptionally Compact Players Profile

Dramatically reduced topline and blade length throughout the set.
