Mizuno Pro M-13 Golf Irons - Steel
The Mizuno Pro M-13 irons build on the legacy of the Mizuno Pro 243, combining classic tour-inspired shaping with advanced multi-material engineering. Designed to produce faster ball speeds in the long irons and greater control in the scoring clubs, the M-13 delivers a progressive performance package while maintaining a consistent profile and forged feel from 4-iron through to gap wedge.
The M-13 features a compact head shape with a thin, progressive top line that appeals to accomplished players. Behind its traditional appearance lies modern internal technology engineered to promote stronger launch conditions and improved ball speed consistency across the set.
The 4 and 5 irons utilise a Pocket Cavity Grain Flow Forged construction, blending high-strength Chromoly 4120 with 431 stainless steel. This design increases structural strength and enhances ball speed potential, delivering improved launch and added distance in the longer irons without sacrificing the soft forged feel.
The mid-irons feature a Micro-Slot Grain Flow Forged construction with a face that is 0.3mm thinner than the previous generation. The increased face flex promotes controlled ball speed and mid-to-high COR performance, producing powerful yet predictable trajectories.
In the scoring irons, the M-13 transitions to a one-piece Grain Flow Forged 1025 Elite construction. This prioritises precision, trajectory control and the soft, stable impact sensation synonymous with Mizuno's forged irons.
The multi-material construction allows for Mizuno's thinnest-ever Contour Ellipse Face at just 1.37mm, approximately 35% thinner than the Mizuno Pro 243. This delivers increased ball speed and enhanced distance while preserving the responsive forged feel players expect.
The Triple Cut Sole incorporates sharper leading edges and relieved trailing sections to improve turf interaction. This promotes consistent strike quality and reliable contact across a variety of playing conditions.
