Mizuno Pro 225 Vs. Mizuno JPX 921 Hot Metal Irons Comparison Overview

It’s sort of a blessing and a curse to have finally decided that your next set of irons is going to be a Mizuno set. It’s a blessing, because you will be making a great investment into your game and you can hardly go wrong with any Mizuno irons.

It can be a curse because there are so many amazing models to choose from. It’s sort of a glut of options. If you are deciding between Mizuno models though, we want to help. Check out our overview of the Mizuno Pro 225 and JPX 921 Hot Metal Irons.

Mizuno Pro 225 Irons Overview

One thing that must be said about the Mizuno Pro 225 irons is that they were meticulously crafted.

Even if you are looking for a couple of long to mid iron replacements for your existing set, the Mizuno Pro 225 irons would be a great choice. The longer irons in this set are made from chromoly which is a high strength to weight steel alloy.

The long irons in this set are supremely wieldy and lightweight. Even from 200+ yards out, they are also very workable. The compact player’s performance head profile and short blades will be a welcome sight to low handicappers.

If you venture to the shorter irons, you will benefit from superior feel in the form of 1025 carbon steel construction.

Mizuno JPX 921 Hot Metal Irons Overview

The JPX 921 Hot Metal irons are clearly intended for lesser-skilled players.

That’s not to say that they lack premium appointments though. Yes, it’s true that the perimeter weighting and variable sole thickness designs are predicated on helping less accurate players hit the ball further; but these features belie the premium construction.

The JPX 921 Hot Metal irons still feature the chromoly alloy steel material. The seamless cup face also works to increase forgiveness on mis-hits. Our testers found that the JPX 921 Hot Metal irons tend to produce a low, piercing shot trajectory but were very predictable and consistent.

Our higher handicap testers were having a much better go of it with the JPX 921’s than with the Mizuno Pro 225’s despite the similar offset.

It’s clear that the JPX 921 Hot Metal irons will be more beneficial to mid handicap players while the Mizuno Pro 225 irons are more advantageous to low handicappers.

Mizuno Pro 225 Irons – First Impressions

With all the hype about these irons, let’s chat about the technology Mizuno have pumped into them.

Like the rest of the Pro range, the Mizuno Pro 225 irons are Grain Flow forged, the face and neck are forged, what is unique about Mizuno is all of their clubs are made in the factory in Hiroshima – Japan, since 1968.

Since 2018 Mizuno have introduced a microlayer of copper underneath Nickel Chrome, this gives you the purest, softest feel we have all come to know and love from Mizuno.

This iron actually has a combination of two forging techniques, the 2-8 iron uses the Grain Flow Forged 4135 Chromoly Face & Neck technique, it also has a COR Forged Hollow Body 28.5g Tungsten weight this gives the iron its unique look as well as producing a higher launch, more consistent flight and incredible ball speed.

The 9-PW has a 1025E pure select mild carbon steel structure, this enhances precision and a more penetrating flight, this helps with the scoring irons, allowing you to attack even the tightest of flags.

Now after all this we were extremely excited to get these onto the range, and let’s be honest there it was love at first sight.

When we put the club down behind the ball we expected a tiny looking head, but we were wrong. Not overly big, but perfect. It was the right amount of thickness to give you confidence.

When we started hitting balls we could instantly see some increase in ball speed, as well as forgiveness. These were for sure not a blade.

We were surprised how workable these are, usually when a club is as forgiving as this, you lose workability, but we were able to hit fades and draws, as well as high and low on demand.

Another issue with the hollow body construction club is you get what they call a ‘hot shot’, this is when the ball flies 10/15 yards further when struck well, now this may sound great, but if you fly the ball into a bunker unexpectedly, then it is not at all. We did not get any of these so called ‘hot shots’, a few flew around 5 yards further, but that can be expected with any iron.

This Mizuno Pro 225 is high launching and forgiving while looking exactly like a blade at address and in your bag.

Mizuno JPX921 First Impressions

The JPX921 irons couple incredibly sleek looks at address and with an amazing forged feel.

The Mizuno JPX921 Forged irons have a beveled trailing edge on the sole which smooths out turf interaction.

This coupled with the obvious amazing feel from the grain flow forging process makes these irons so pleasing to swing.

The blades of these muscle back irons are pretty compact and there is a part of the back area that has been milled to increase stability and thin out the back wall a bit.

These irons also feature the notorious chromoly construction which contributes to the soft feel.

The Mizuno Pro 221 is designed on years and years of incredible Mizuno blade irons, through the years they have made the irons more playable by small improvements in shape and weight placement.

Like the other models in the range it is Grain Flow Forged, with a soft copper underlay, giving the Pro 221 your traditional Mizuno sound and feel.

Who Are The JPX 921 Forged Irons For

For starters, these irons would work great for any player who wants to emphasize precise feedback and feel as a low handicapper and beyond.

We can’t emphasise enough that you’re not going to want to invest in these irons if you’re just starting out with golf. These are performance irons through and through for the better players.

While the JPX921 Forged irons do give impressive distance the compact heads and points of design emphasis will be lost on beginners who will struggle to find the sweet spot consistently, if they don’t find the higher price point off putting enough already.

The JPX921 irons did play more accurate around the pin and were more forgiving than many forged Irons with their toe bias weighting.

Perfect for single digit handicap pin hunters around the world.

The JPX921 Family

The JPX921 Forged irons are joined by the JPX921 Tour and JPX921 Hot Metal irons.

The JPX921 Tour irons produce surprisingly straight shots for tour-grade clubs. They have sleek, compact heads and feature the same grain flow forging construction.

The JPX921 Hot Metal irons are the most forgiving in the family with a Cup Face design that preserves ball speed around the perimeter.
