Mizuno just formally announced the JPX 925 Forged and JPX 925 Forged Black irons. This seems to now complete the JPX 925 line, with their forged offering that is a bridge between their game improvement irons and their Pro line. The Pro line was released last year as the 241 (blade), 243 (cavity style), and 245 (hollow body) clubs. Mizuno announced on 1/7/2024 the Pro S-3 which seems to fit between the 241 and 243, making for a very crowded space.
Key Features of the Mizuno JPX 925 Forged Irons
1. Midsize Cavity Design for Pro to Mid-Handicap Players
- Head Length: 79.5 mm which is slightly smaller than the Hot Metal Pro
- Material: Grain Flow Forged HD, apparently using a new process where they can make the grain lines more compact in the hitting area. This is likely mainly in the scoring irons made from 1025 carbon as opposed to the 4-7 which are made from 4020 chromoly.
2. CORTECH Design with Contour Ellipse Face
Basically allows for a thinner face material and adjusted thickness throughout the face to try to keep consistent speed on off center strikes.
3. Materials That Elevate Performance
Long Irons (4–7): Multi-Material Chromoly Construction
- Forged from Chromoly 4120, a harder steel that provides faster ball speeds. As I play the 923 Forged, I can say the Chromoly 4120 feel different from 1025, but not in a bad way. The Mizuno irons have a very solid, satisfying feel.
Short Irons (8–GW): Pure Select Mild Carbon Steel
- Forged from 1025E Pure Select Mild Carbon Steel
- Offers precise control and the iconic “buttery” Mizuno feel
Technological Innovations That Stand Out
Balanced Stability Frame
Marketing? Or does it really optimize the shape for optimal vibration and sound? Either way, they seem to continue the Mizuno tradition of having excellent feel.
Triple Cut Sole
The Triple Cut Sole is engineered to improve turf interaction, making these irons versatile across various lies and conditions. It’ll be interesting to hear feedback from people on how the turf interaction actually changes from the 923 Forged. This to me seems to be one of the bigger changes.
Harmonic Impact Technology
Head geometry, combined with Acoustic Sound Ribs, is credited by Mizuno as helping provide a solid and satisfying sound with every strike.
Has an impressive looking black finish available for a slight upcharge, which so far seems to be getting the most praise. Unfortunately the black version does not seem to be available for lefties.
I plan to update this page as more detailed reviews becomes available.
