Mizuno JPX923 Forged Iron Set 4-PW, GW (8-Piece) Steel Shaft

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.
