What’s new? How much does it cost? And, what are the performance gains? Max McVittie brings you the lowdown on the Mizuno M13 and M15 irons
Mizuno’s flagship Pro range has garnered a lot of success over recent years and now the brand has expanded it with the all-new modern series. It debuts with two new iron sets; the M13s and the M15s.
Designed to blend contemporary performance engineering with the brand’s revered forged heritage, the new irons give golfers a more finely tuned range of choices. Essentially, they are built for golfers who want classic forged feel with a noticeable bump in speed and playability.
To find out how just how good they are, here’s everything you need to know about Mizuno’s latest Pro irons…
Mizuno M-Series Irons: Everything You Need To Know!: The Technology
The M-13, successor to the Mizuno Pro 243, blends classic tour-preferred shaping with modern multi-material construction. It employs a three-part forging strategy that adjusts performance throughout the bag while maintaining a unified feel from 4-iron to wedge.
In the four and five irons, Mizuno introduces a Pocket Cavity Grain Flow Forged structure that combines Chromoly 4120 with 431 stainless steel. This allows the brand to include their thinnest ever Contour Ellipse face, which is around 35% thinner than the face used in the 243 irons.
Mizuno say the result is faster ball speeds and more stable long-iron performance.
In the shorter irons, there has been a shift to a Micro-Slot Grain Flow forged design, again with a slightly thinner face than the previous generation of irons. The ball speeds are more controlled as a result.
Mizuno also incorporates Harmonic Impact Technology, a copper underlay and a full cavity ABS badge to fine-tune the vibration profile. A redesigned Triple Cut Sole helps the club glide through varying turf conditions, while the Nickel Chrome Satin Brush finish provides a refined, glare-reducing aesthetic.
With the M-15, Mizuno builds on the success of the Mizuno Pro 245 irons.
The 4–8 irons feature Mizuno’s next-generation Contoured Ellipse Face, part of the company’s CORTECH evolution. This multi-thickness forged face is paired with a hollow body design, boosting ball speed and consistency without sacrificing forged feedback.

These mid irons also combine a Grain Flow Forged 4135+ Chromoly face and neck with a stainless-steel back to increase rebound and ball speed.
From the 9-iron to gap wedge, the M-15 transitions into a partial hollow 1025E Grain Flow Forged HD body paired with a stainless-steel back. Control and maneuverability has been increased in these higher lofted irons.
Additionally, the irons benefit from a refined ole geometry with added bounce for more reliable turf interaction.
