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.

  • RELATED: Mizuno M15 Irons Review: Distance gains without losing control

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.

About the author

Max Mcvittie

A bit of a late bloomer to the game of golf, Max fell in love with the sport when he attended Saturday coaching sessions down at his local golf club after being inspired by friends and family members.

Max has remained a member of Eden Golf Club in Carlisle for a number of years now as he looks to get his handicap down into single figures. Most of his golfing career has been spent battling a permanent slice off the tee, which has led to some ugly rounds.

Having studied at the University of Sunderland, Max is starting out his dream career in sports journalism. During his time at university, he picked up valuable work experience at Reach PLC, BBC Radio Cumbria and GiveMeSport, whilst also getting work published in the Teesside Live. He also spent time working at a local weekly newspaper, Eskdale and Liddesdale Advertiser, as a general news reporter partially covering some local sport just north of the border in Langholm.

Max has just started his journey with the NCG working as the assistant equipment editor. He looks forwarded to reviewing the latest golf equipment, taking up an interest in reviews when buying his first golf club, a Cleveland RTX wedge.

With his bag not going under too many changes throughout the last few years, Max carries an M3 driver, Titleist GT3 Fairway Wood, M2 hybrid, a set of M2 irons, Callaway Jaws wedges and a TaylorMade Spider putter. And yes, Max is a bit of a self-proclaimed TaylorMade fan boy.
