Mizuno have introduced the latest additions to the Mizuno Pro range, 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.

It’s been engineered for players looking for a touch more speed, forgiveness and playability, while maintaining the unmistakable Mizuno Pro shaping and feel.

The Modern Series debuts with two distinct models, each created with a specific type of ball striker in mind. The M-13 brings tour-preferred proportions and a faster, more consistent flight profile, while the M-15 offers higher launch and additional forgiveness that blends smoothly through the set.

Both retain the craftsmanship and forged heritage that sit at the heart of every Mizuno Pro iron.

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.

In the 4 and 5 irons, a Pocket Cavity Grain Flow Forged construction merges Chromoly 4120 with 431 stainless steel, enabling Mizuno’s thinnest ever Contour Ellipse Face, just 1.37mm thick, around 35% thinner than the Mizuno Pro 243.

This innovation unlocks higher ball speeds and distance while keeping the responsive feedback expected from a forged iron.

Moving into the 6, 7 and 8 irons, a Micro-Slot Grain Flow Forged construction with a face 0.3mm thinner than its predecessor increases flex and delivers controlled speed gains with a mid-to-high COR performance.

From 9-iron through to gap wedge, a single-piece 1025 Elite forging prioritises precision, control, and the renowned soft impact feel that has defined Mizuno’s short irons for decades.

Mizuno’s Harmonic Impact Technology, combined with a copper underlay and full cavity ABS badge, fine-tunes vibration patterns and delivers a clean, tour-ready appearance. The Triple

Cut Sole introduces sharper leading edges and bevelled trailing relief, ensuring dependable turf interaction from every lie.

Completing the design, a Nickel Chrome Satin Brush finish reduces glare and reinforces the premium aesthetic.

The M-15, successor to the Mizuno Pro 245, offers a fully integrated progression of performance from long iron to wedge.

Each section of the set is designed with a specific purpose, creating smooth transitions in both shape and feel throughout.

At the core of the design lies the Contoured Ellipse Face, the latest development of Mizuno’s CORTECH technology, which defines the 4–8 irons. This multi-thickness forged construction, supported by a hollow body design, optimises ball speed and consistency while preserving the soft, responsive feel Mizuno players prize.

To improve launch and stability, tungsten weighting of 51g in the long irons and 50.3g in the mids has been strategically suspended within the head, helping produce straighter, more forgiving performance.

The long and mid irons pair a Grain Flow Forged 4135+ Chromoly face and neck with a stainless-steel back piece for additional rebound. The 9-iron to gap wedge transitions into a partial hollow 1025E Grain Flow Forged HD body with a stainless back, a construction that emphasises control, precision and manoeuvrability.

Refined sole geometry with added bounce encourages a cleaner entry and smoother exit through the turf, maintaining consistency across all course conditions.

Mizuno’s Harmonic Impact Technology and copper underlay reduce sound pressure around the 6kHz frequency, producing the soft yet solid strike that Mizuno players instinctively recognise.

Finished in Premium Nickel Chrome Satin, the M-15 brings a contemporary look with tour-informed shaping.

Together, the M-13 and M-15 mark the start of the Mizuno Pro Modern Series, joining the Signature Series (S-1 muscleback and S-3 cavity) to complete the Mizuno Pro line-up.

While the Signature Series continues Mizuno’s most traditional tour iron lineage, the Modern Series introduces new-generation solutions in speed, stability and shot-height control, all within the classic, compact profiles trusted by elite players.

The result is a clearer, more refined Mizuno Pro structure, one that offers golfers the freedom to match head design to playing style without ever losing the forged identity that defines Mizuno.

These new additions seamlessly blend cutting-edge technology with the unmistakable Mizuno feel, delivering precision and versatile performance for the modern golfer.

At the heart of the JPX 925 Forged series is the CORTECH Design with its revolutionary Contour Ellipse Face.

This advanced multi-thickness face profile optimises ball speed across the entire surface, ensuring explosive performance and forgiveness even on off-centre strikes.

Combining both the forgiveness of the Hot Metal series with the refined feel of their single-piece forged irons, the design offers unparalleled versatility.

The innovation behind the Contour Ellipse Face required the development of entirely new construction methods, showcasing our commitment to pushing the boundaries of engineering excellence.

True to our reputation for forging excellence, we employ our Grain Flow Forged HD process at our Hiroshima facility.

The long irons (4-7) in the JPX 925 Forged series are crafted from Chromoly 4120, a material known for its exceptional strength and malleability, enabling higher ball speeds and easier adjustability.

In contrast, the shorter irons (8-GW) are forged from 1025E Pure Select Mild Carbon Steel, a material that delivers superior control, precision, and the legendary buttery feel Mizuno players expect.

Together, these materials ensure a flawless transition through the set, offering the perfect balance of speed, precision, and feedback.

Adding to their versatility is our innovative Triple Cut Sole design, meticulously engineered for enhanced turf interaction across all lies and conditions.

The leading edge is gently bevelled to ensure a clean entry into the turf, while the hard-cut trailing edge facilitates a smooth exit for uninterrupted ball contact.

This design, paired with optimised weighting, gives players remarkable control and confidence, even in the most challenging playing environments.

WHEN WILL THEY BE AVAILABLE

Aesthetics play a vital role in the JPX 925 Forged series, which debuts with two stunning finish options.

The Traditional Satin Chrome provides a timeless, classic look that will appeal to traditionalists, while the Forged Black offers a bold, contemporary option with reduced glare, exuding modern sophistication.

The JPX 925 Forged series is a testament to our relentless pursuit of innovation and perfection.

Designed for golfers seeking speed, precision, and feel, these irons redefine expectations in the forged category.

The JPX 925 Forged and JPX 925 Forged Black will be available at authorised retailers and online from Monday, 3rd February 2025.

The new JPX925 Hot Metal range comprises three models, each tailored to meet the unique needs of different golfers – Hot Metal, Hot Metal Pro, and Hot Metal High Launch – although combination sets of irons from two or all of the models can be custom-fitted to suit player preferences.

The range benefits from a new colour-coding system on the back of each clubhead, simplifying the differentiation of models. This system features a white marker for the Hot Metal, black for the Hot Metal Pro, and blue for the Hot Metal High Launch, allowing for quick and easy identification.

JPX925 Hot Metal

Built for maximum speed and consistency, this model features the innovative CORTECH Design and Contour Ellipse face, which provides unparalleled distance control.

RRP: £150 per iron, £900 (5-PW)

JPX925 Hot Metal Pro

For golfers seeking a slimmer, more refined profile, the Hot Metal Pro combines advanced technology with a compact design. The inclusion of Chromoly 4140M, a high-strength material known for its excellent strength-to-weight ratio, allows for a thinner face and a pliable hosel, enabling precise fitting.

RRP: £165 per iron, £990 (5-PW)

JPX925 Hot Metal High Launch

This model is designed to offer maximum launch and spin, making it ideal for golfers who need help elevating their shots. It features the same cutting-edge technology as its counterparts but in a wider, easier-to-hit package.
RRP: £150 per iron, £900 (5-PW)

The JPX925 Hot Metal Irons also benefit from Mizuno’s latest technology, such as:

• The CORTECH design and Contour Ellipse Face introduce a multi-thickness face profile that is 30% thinner than its predecessor, enhancing ball speed and ensuring maximum speed retention throughout the impact zone.
• Multi-material construction incorporates tungsten weighting in the 4-7 irons, positioning the weight low to facilitate a higher launch and a lower sweet spot.
• Seamless one-piece cup face geometry of the irons, which maximizes the rebound area for unparalleled ball speed across the entire face.
• Variable sole thickness enhances the overall face flex area, contributing to increased CORAREA (Coefficient of Restitution), while the balanced stability frame improves control without sacrificing forgiveness.
• Tour-preferred vibration and sound, thanks to Mizuno’s Harmonic Impact Technology and Acoustic Sound Ribs.

ON SALE DATE

JPX925 Hot Metal Irons will be on pre-sale from September 5 and available for purchase from September 19.

The post Mizuno launches JPX925 irons appeared first on Golf News.

The series includes a muscle back blade (Pro 241), a tour cavity back (Pro 243), and a hollow body construction head (Pro 245), but the new irons have some changes in aesthetics and technology that have made the irons even more desirable.

Mizuno Product Director Chris Voshall said: “Everything about the new Mizuno Pro 241/243/245 is pushed to the extreme – from technology to more streamlined playing profiles. Each model has become better at its specific job, more distinct, yet able to be blended when required.”

David Llewellyn, Mizuno’s Director of R&D, added: “Other manufacturers have widely adopted Mizuno’s work to elevate the performance of elite player’s irons. What now sets Mizuno apart is the ability to apply precise manufacturing techniques learned at our long-standing forging plant in Hiroshima, Japan, to increasingly complex designs.”
