Mizuno Pro 243 Irons [4-PW][RIGHT][STIFF]

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. Performance improvements are only made possible through the long-term relationship between Mizuno’s R&D team and its exclusive Grain Flow Forging plant in Hiroshima, Japan.

Grain flow forged hd in hiroshima, japan: From a single billet at Mizuno’s exclusive facility – where Mizuno irons have been produced since 1968.

Soft copper underlay: A microlayer of copper beneath Nickel Chrome – an additional touch to enhance the feel of our Grain Flow Forged heads.

1025E Pure select mild carbon steel:

Solid feel and control where most needed, with modern lofts to maintain even distance gapping through the set.

Harmonic Impact Technology: Applied to closely match the vibration patterns identified with a soft muscle-back feel.

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.

FULL SATIN BRUSH: A less reflective finish in keeping with the overall modern appearance.
