Mizuno JPX 900 Irons Review – How Do These Clubs Stack Up?

To play at your best you need the right equipment. There is no one size fits all and Mizuno are acutely aware of this. It is for this reason that they have introduced three new ranges of their JPX 900 irons.

There is something for everyone and each one has the technology and design features to work best with your skills and abilities behind the clubs.

While we will focus on the forged irons that are suitable for a wide range of players, also consider the Hot Meal Irons for beginners as well as the Tour Irons for better players.

Unless you are just starting out or a very low handicap golfer you are solid build and consistent performance of the Forged JPX 900 Irons.

They are a top-selling favorite for many and for good reason. Not only do they perform well, but they are also one of the best looking irons you will see.

Things to consider before buying new irons

There is no doubt that your choice of irons will have a significant effect on your game so take care when selecting. Before we go any further with this review, it is important to understand the difference between a forged and a cast gold iron.

Both are important but there are a few differences that are necessary to understand before making a selection.

The majority of irons fall into two categories:

Forged Irons

This is the original way metal was shaped by a blacksmith. The metal is hammered and worked into shape and then perfected by grinding, milling and polishing.

This gives a solid single iron that is generally less forgiving but has greater control and workability.

Modern technology, materials, and procedures have made forged irons more forgiving and accommodating for the average golfer while retaining their traditional sound, feel and control.

Cast Irons

As the name suggests, these irons are produced by pouring mouton metal into a mold. This allows for more intricate work and details in the construction and gives a bit more flexibility in materials.

The weighting is often more precise and the process is less expensive than forged irons.

Both options have advantages and disadvantages and modern technology has blurred the lines between the two options. It is, however, still important to find the best option for your game.

Other things to give serious consideration to are the forgiveness, accuracy, loft, and distance of the irons.

Mizuno JPX 900 Irons Review

Mizuno has really hit the spot with its range of JPX 900 Irons. There are three options available.

JPX 900 Hot Metal Irons

These are best suited for higher handicap players and even beginners. Mizuno has used a new metal in the technology behind these irons known as chromoly.

These irons are extremely forgiving and deliver amazing balls speeds and distance.

JPX 900 Tour Irons

Those fortunate enough to play off a very low to scratch handicap will appreciate and benefit from the power and playability of these magnificent irons.

They contain no boron, look absolutely incredible and perform with aplomb.

For more specific on the three types of Mizuno JPX 900 Irons and a demonstration, check out this video.

JPX 900 Forged Irons

These are great looking and performing irons for the more mid to low handicap golfers.

They use boron much like Mizuno did with the popular JPX 850 Forged Irons. They give you a great balance of playability with distance and forgiveness.

While these are all great options, depending on your skills and experience, we will be focusing on the forged irons. Unless otherwise stated, we will be reviewing and referring to these.

They are best suited to the average golfers. Not for very low handicap golfers and best not for absolute beginners.

Pros
  • Boron gives great strength
  • Good speed and distance
  • Great weighting for high MOI and minimal twisting
Cons
  • Not the best feel in this category
  • Feedback is average at best

And, given that they are designed for low to medium handicap players, take a look at an average golfer with these irons:

Features & Benefits

Mizuno has not introduced much new technology in these irons. What they have done, is build on past success and fine tune the irons to ensure they are even better.

Boron Steel

These forged irons use Boron steel, 1025 Boron steel to be precise. This adds about 30% additional face strength to the irons and allows for better application of other design features and technologies. It helps a forged iron deliver faster ball speeds for better distance.

Variable Face Thickness

Many manufacturers are now using this technology and Mizuno has introduced it in the JPX 900 Irons. This, combined with an extended pocket cavity thanks to the boron gives a weight saving of 21.5g.

Weighting

This weight saving allows Mizuno to weight the face around the perimeter of the PowerFrame. This gives you more forgiveness, less twist, and a greater MOI.

Milled pocket cavity

This helps to get greater ball speed and distance across the face and would not be as good without the addition of the Boron.

Look

While we all care about performance first and foremost we still want out clubs to look great. Mizuno does not disappoint. One thing about this range is that they are really great looking clubs.

Something I really like about these irons is that they have the look of real player’s irons while still being practical for a medium golfer.

Alternatives To The Mizuno JPX 900

Ping G700 Irons

Technology is a big factor with modern irons and Ping are one of the leading manufacturers in this regard. They have used a hollow-body design with the G700 Irons.

This shaves weight off the head allowing it to be positioned for better results.

Combined with the maraging face and other design features, you will get a set of irons that are easy to launch, forgiving and give you a good distance.

Wilson C300 Irons

These popular irons are suitable for most players. The key technology is the 10 Power Holes. These Utherane-filled holes gove the irons an amazing feel, sound, and performance.

The power holes extend around the face for good forgiveness and distance. You will also get good feedback and the distance is exceptional.

Callaway X20 Irons

If you want a top quality set of irons without breaking the bank, the Callaway X20 irons are an option to look at. They are proper game improvement irons that will suit most golfers from the lower middle to higher handicap.

They have a great feel and are accurate irons. The low COG will minimize off-center hits and give more forgiveness and more accuracy.

Conclusion

It is hard to argue with the feedback on these irons, from the average golfer to the pros. They do pretty much what they promise and look good while delivering great speed and distance.

If you want players looking iron that will still give you forgiveness and help with distance and accuracy, these are a great option.

They would not be ideal for a pro and not suit an absolute beginner. For everyone else, there is a lot to be gained from using the Mizuno JPX 900 Irons. They are hard hitting, straight hitting irons with control and accuracy.

As an added bonus, they look spectacular.
