Mizuno JPX 923 Hot Metal Pro Irons

Players seeking maximum forgiveness and distance who prefer a smaller head and thinner topline, your search ends here. The Mizuno JPX 923 Hot Metal Pro irons feature the same material and technologies as the standard Hot Metals, with less offset, a classic look and added workability.

Features of the Mizuno JPX 923 Hot Metal Pro Irons

435 Nickel Chromoly

The JPX 923 irons are crafted from New 435 Nickel Chromoly, which is 35% stronger than Mizuno's original Chromoly. This allows for an 8% thinner face resulting in higher ball speeds.

Players Speed Cavity

The Players speed cavity offers a compact design and minimal offset for confident ball-strikers seeking maximum ball speed while maintaining playability.

Mizuno's all-new V-Chasis delivers a solid, satisfying vibration pattern through impact (even though the face is 8% thinner)

Seamless Cup Face

The JPX 923 irons feature seamless face construction, which delivers the deep center of gravity necessary for higher launch and optimal landing angles.

Extended Sole

The thinnest part of the sole is extended 18% wider, creating a bigger high-energy area for higher ball speed on more shots.

Non-Reflective Finish

Mizuno's JPX 923 finish is non-reflective and chrome plated to reduce bright light glare.

Quick Questions 

What is the difference between the JPX 921 and the all-new JPX 923?

The JPX 923 line from Mizuno features an all new V-Chasis with a Seamless cup face. These irons, the JPX 923, are made from a 35% stronger (435 Nickel Chromoly) steel that feels better coming off the club face and creates more ball speed. The new Seamless Cup Face on the JPX 923 also improves vibration patterns at impact for a more satisfying feel when compared to the JPX 921.


Which irons should I play?

These irons feature modern strong lofts and will be geared towards maximum distance and forgiveness.


JPX 923 Hot Metal - The JPX 923 Hot Metal is perfect for the mid to low handicapper (7-15) who is looking for a combination of high launch, high ball speed, and high forgiveness. The JPX 923's deliver solid, consistent performance on each and every shot. They will be more forgiving then the Hot Metal Pro and more workable then the Hot Metal HL. The Hot Metal is the most popular choice in the new Mizuno JPX 923 product line.


JPX 923 Hot Metal Pro - The JPX 923 Hot Metal Pro is perfect for the low handicapper (0-6) which is looking for more traditional lofted irons, with a thinner topline, and a more workable profile.
