Mizuno JPX 923 Forged Irons

A mid-sized, full body Grain Flow Forged iron delivering a perfect balance of ball speed, stability, and feel.  Our 3rd generation of Chromoly Forging (4-7 iron) incorporates a milling slot that extends wider to heel and toe.  Paired with an even thinner clubface it creates our highest one-piece forged ball speeds from an even greater portion of the clubface.  The irons showcase a thinner top line throughout, plus compact scoring irons (8-GW) and beveled sole for improved turf interaction.

Technical details

  • Grain Flow Forged HD: One-piece Grain Flow Forged HD from 1025E Pure Select mild carbon steel at Mizuno's iconic facility in Hiroshima, Japan – where Mizuno irons have been produced since 1968.
  • Chromoly 4120: With its high strength to weight ratio and malleability, Chromoly allows for a high strength face with a bendable hosel for fitting.
  • Harmonic Impact Technology: Fine tuned head geometry delivers ideal impact feel and feedback
  • Back Milling: CNC milled from the sole up creating a larger area of minimum face thickness for consistently increased ball speeds
  • V-Chassis: Engineered via Mizuno's Harmonic Impact Technology, the V-Chassis allows the top line to be thinner without sacrificing feel and sound.
  • White Satin Brush Finish: A modern elegant, yet durable non-glare finish
