Mizuno Pro M-13 Irons

Overview

The Mizuno Pro M-13 and M-15, part of the all-new Modern Series. Sitting alongside the existing Signature Series (S-1 and S-3), the Modern Series represents a fresh evolution in forged performance. Engineered for players seeking a bit more speed, forgiveness, and playability, while maintaining the unmistakable Mizuno Pro shaping and feel. The Modern Series debuts with two distinct models, each designed for a specific type of ball striker. The M-13 features tour-preferred proportions and a faster, more consistent flight profile, while the M-15 delivers higher launch and additional forgiveness that blends smoothly through the set. Both retain the craftsmanship and forged heritage that define every Mizuno Pro iron.

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.

Features

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 utilise 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 prioritises 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 bevelled 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.
