Mizuno Pro 243 Steel Irons

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.  

“The Mizuno Pro 243 is the model that’s advanced the most, mainly due to evolution on the manufacturing side.  It’s one thing for the R&D team to design a thinner face iron with stronger materials in the CAD world – but something else to have it Grain Flow Forged to those specifications and strength requirements.” DAVID LLEWELLYN – Director of R&D

Grain Flow Forged HD in Hiroshima, Japan

One-piece Grain Flow Forged HD from 1025E Pure Select mild carbon steel at Mizuno's exclusive facility - where Mizuno irons have been produced since 1968.

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.

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 8-GW

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

Harmonic Impact Technology

Applied to closely match the vibration patterns identified with a soft miuscle back feel.

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.

Increased bounce angle

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

Full Satin Brush

A less reflective, modern finish.

“The Mizuno Pro 243 looks much more compact than its predecessor, even though the performance has stepped up.  The long and mid irons are flying far enough, that we’ve had to modernise the lofts in the scoring irons. Mizuno Pro isn’t stuck in tradition – we’re led by performance above what might be expected historically.” CHRIS VOSHALL – Product Director
