Mizuno’s JPX923 irons are engineered for custom performance. Five unique iron models created from three specific metals - based on Swing DNA data from over 350,000 real golfers. The expanded head options combine with one of over 50 custom shafts for specific trajectory, ball speed and ease of use. This creates options for elite tour players, slow swinging amateurs and every player in between.
Three metals. Five options. All distinctively Mizuno.
Introducing Nickel Chromoly – A new material with so much additional ball speed, our engineers switched their focus to feel and stopping power. At 35% stronger than our original Hot Metal material, 4335 Nickel Chromoly enables a high-energy 8% thinner clubface. Combined with Mizuno’s vibration controlling V-Chassis and deep CG design, the JPX923 Hot Metal irons are as enjoyable and controllable as they are long.
“As we get thinner and thinner on the clubface to enhance ball speed – the next challenge becomes sound and feel. The new V-Chassis reinforces the clubhead in a different way – that gives the extra performance hand in hand with improved feedback.”
- DAVID LLEWELLYN – R&D Director
Studying over 175,000 recorded Swing DNA fitting sessions with real golfers per year – Mizuno’s R&D team highlighted the need for three distinct player needs and launch patterns.
“There are so many different kinds of players looking for increased ball speed from their irons, we needed more options for them at a fitting level. The custom studios use shaft selection incredibly well to help with launch angle or slower swing speeds, but the JPX923 Hot Metal HL gives them a great new tool to work with.”
- CHRIS VOSHALL - Director of Product
JPX 923 Hot Metal Irons are ideal for golfers seeking a full speed, high stability cavity for straight flight and distance. Forgiving on off hits, they are best suited to mid/high handicaps.

I wanted a specific configuration for my drive and this was easy and straithforward. I had a slight doubt with regards to the swingweitght and the tork wrench and was quickly answered via the chat. The drive was packaged very professionally. Really impressed with the entire process and the product received.

I’m loving these irons. Great feel, great workability, great distance. I was hesitant to buy them because I was worried about yardages being too long. I’m glad I didn’t let that steer me away from these because they are fantastic irons

Bought my first new driver in 6 years, and it was a great decision. Bought the Qi35 in gold to go with my green and gold golf bag. The club head is lighter then my M5, and I am able to work the ball better and more consistency. Best buy of 2025.

I had old sm6 Vokeys and decided it was time for an upgrade. Heard and saw great things about the MG4s and decide to go with them. I purchased 50-SB, 54-SB, and 58-LB and I have to say these things rip. The spin I can achieve with these is incredible. TaylorMade for the win.

Great Replacement set for my 25+ year old original clubs. Quality is great and received them in a week. Took them to the range twice already and am very pleased, looking forward to play some rounds to get a real feel for them.
