Mizuno requires all LH M-13 iron sets other than Steel Stiff 4-PW sets be built custom. MIZUNO PRO M-13 IRONS Legacy Redefined The M-13, successor to the Mizuno Pro 243, combines traditional head shaping with modern construction to create a set that offers more speed through the long irons and greater precision in the scoring clubs. Its three-part forging story adapts performance across the bag while preserving a consistent feel and look from 4-iron to wedge. Integrated Construction A maneuverable and compact head size with a thin graduated top line throughout the set. The M-13 brings tour-preferred proportions and a faster, more consistent flight profile. Pocket Cavity Grain Flow Forged (4–5 Iron) The 4 and 5 irons utilize a Pocket Cavity Grain Flow Forged construction, combining Chromoly 4120 with 431 stainless steel to deliver increased strength and higher ball speed potential in the long irons. Micro-Slot Grain Flow Forged (6–8 Iron) The 6, 7 and 8 irons feature a Micro-Slot Grain Flow Forged construction with a face 0.3mm thinner than the previous generation, increasing face flex to deliver controlled ball speed with mid-to-high COR performance One-Piece 1025 Elite Forging (9-GW) From 9-iron through to gap wedge, a one-piece Grain Flow Forged 1025 Elite construction prioritizes precision, trajectory control and the soft, stable impact feel synonymous with Mizuno’s scoring irons. Contour Ellipse Face This multi-material construction enables Mizuno’s thinnest-ever Contour Ellipse Face at 1.37mm, approximately 35% thinner than the Mizuno Pro 243, increasing ball speed and distance while maintaining the responsive feel expected from a forged Mizuno iron. Triple Cut Sole The Triple Cut Sole features sharper leading edges and beveled trailing relief, promoting consistent turf interaction and reliable contact from a wide range of lies and swing conditions. Harmonic Impact Technology Harmonic Impact Technology, paired with a copper underlay and full cavity ABS badge, fine-tunes vibration frequencies to deliver a soft, controlled feel and a clean, tour-preferred sound at impact. Nickel Chrome Satin Brush Finish A Nickel Chrome Satin Brush finish reduces glare at address while reinforcing the refined, premium appearance expected of the Mizuno Pro line.
