Mizuno JPX923 Tour Irons Review

Aimed at the better players from what Mizuno described as “Pro to Elite Amateurs”, the Tour irons are the premium choice of the range.

The irons are crafted one-piece Grain Flow Forged, but also have a copper underlay for an even better feel off the club face.

The Tour model is designed with a shallow cavity, has Mizuno’s new V-Chassis and also features a thinner topline than in the JPX921 version.

The blade length of the elite performer is shorter in 6-iron to gap wedge compared to the other models in the series.

Mizuno JPX923 Hot Metal Irons Review

Mizuno have given the Hot Metal and Hot Metal Pro a makeover in the JPX923 range, but have significantly also added a new model – the HL.

The three options all feature a stylish and forgiving cavity back design that has been produced to generate explosive ball speeds off the face.

Produced from a 4335 Nickel Chromoly, the Hot Metals have been made 35% stronger than our original material used in this model. That has enabled Mizuno to make the clubface 8% thinner and generate even more energy at impact.

All three models also feature the new V-Chassis, which reduces vibration, have a deep CG and are incredibly forgiving and long.

The Hot Metal is the most stable and standard of the trio and produces a straight ball flight and eye-catching distance. It is suited to mid to high handicappers.

The Hot Metal irons are available in 4-iron (19 degrees) to lob wedge (60 degrees).

The Pro is more compact in design and shape is aimed at low to mid-handicap golfers with minimal offset in this one piece Nickel Chromoloy Cavity iron.

The HL is the newcomer and targetted at mid to high handicap golfers who need additional help getting the ball in the air.

The High Launch of this iron, which features a Max Forgiveness Speed Cavity design, makes it an ideal choice for slow swing speeds looking to generate more yardage from shots.

The HL also inspires added confidence with the largest clubhead of the three Hot Metal irons. They are available in 5-iron (25 degrees) to sand wedge (55 degrees).

Verdict: Are Mizuno JPX923 irons any good?

The JPX921 irons were widely acclaimed and the next generation from Mizuno are going to make a big impression into 2023 and beyond.

Improvements have been made to the 921s by studying data from more than 350,000 golfers from around the world to extract more distance, carry and forgiveness.

The addition of a high launch version of the Hot Metals is an interesting move and fills a void previously not catered for and Mizuno certainly have golfers of all abilities covered in the new JPX923 irons.
