Overview

The Japanese Performance Extreme (JPX) iron range is the Mizuno lineup that signifies a new aggressive range of irons that are distance driven.

It features dampening bars to enhance the feel and strike sound. Let’s compare them using the factors below:

Construction

The irons have an extremely reactive feel and an improved MOI. They are stable in full swings and offer quick distance boosts.

They have the re-engineered CoFTECH face, which is 0.2mm thinner across the center point.

Forgiveness

The combination of the Mizuno JPX 921 seamless cup face design and its variable face thickness makes it a forgiving iron.

While it’s not the most considerable forgiving iron, it offers premium forgiveness instilled in its relatively compact head.

Furthermore, the seamless cup face design enables an improved flex across the hitting zone.

Generally, the JPX 921 Hot metal irons offer more forgiveness. In fact, it’s the most powerful and forgiving iron in the JPX collection.

Conversely, while the JPX 921 Hot Metal irons are the most powerful and forgiving irons of the brand, they are not explicitly designed for high handicappers.

They are ideal for players who prefer a larger club head with excellent distance.

They are the game improvement entry irons that feature essential forgiveness and distance technology to offer high launch, straighter shots, faster speed, and higher distance.
