Features of the Mizuno JPX 921 Forged irons
While the JPX921 Hot Metal irons have 4140M Chromoly, the Forged iron model uses 4120, which results in the fastest ball speeds when compared to previous models.
While the Hot Metals have stronger lofts for added distance, the JPX 921 Forged irons ball speed will help better players gain excellent distance with every club and from every situation.
As is the case with most Forged irons, it has a blade length and design. This shorter blade length than most irons will help golfers add shape to their shots with ease.
Hitting a big fade around a tree in the fairway just became much easier for most golfers with this feature.
The Mizuno JPX 921 Forged model also offers a bevelled trailing edge and reduced offset. Both of these features combined will provide more forgiveness for golfers and offer straighter shots on mishits.
CNC Milled Clubhead
Forgiveness in a Forged iron is very hard to find, but these Mizuno clubs will help lower handicaps keep their shots straighter with a CNC Milled back.
By implementing a larger back slot, Mizuno was able to provide added stability to their clubs and make the Mizuno JPX 921 Forged irons more forgiving than most forged iron models.
While the CNC Milled back slot gives forgiveness, the stability frame adds even more to the JPX921 Forged irons. Just like the Hot Metal and Hot Metal Pro irons, the Forged iron set utilizes perimeter weighting to provide all around forgiveness from heel to toe.
In addition, it uses toe bias weighting to counter off center hits, helping make the golf ball launch higher and straighter on poor contact. All these features create more stability for better forgiveness for the occasional mishit.
Excellent Feel and Sound
Mizuno makes some of the best clubs for sound and feel, and the JPX 921 Forged irons live up to the company’s reputation. These clubs will provide golfers with a great sounding impact that matches the quality of the shot.
The turf interaction of the Forged iron set provides a soft feel through contact with the ball, and this will help inspire confidence on the course.
The JPX 921 Forged irons have an aesthetic pearl brush finish that minimizes distractions when standing over the ball. They are also slightly thinner than previous models, which provides more speed and control over the trajectory and shape of your shots.
Pros and Cons
Great for shot shaping
Fastest ball speeds
Less forgiving than other models
One of the best benefits of using blade length irons is the shot shaping control you gain. The Mizuno JPX921 Forged irons are great for adding a draw or fade to any shot.
Having this ability will help you get out of a lot of tough situations. For example, if you’re tee shot ended up behind 20 yards behind a tree and you still have 170 yards into the green, you could still reach the green in two with a slinging draw over the fairway.
The lighter weight and thin club head also help to create fast ball speed with every club. This increase in speed will lead to farther distance with each club, and everyone loves being able to carry a couple extra yards.
As great as the Mizuno JPX 921 Forged irons are, there’re a couple of cons. First off, the JPX 921 Forged irons are much less forgiving than the Hot Metal and Hot Metal Pro irons. While the compact blade design adds more speed and control due to the thin clubhead, this results in even less forgiveness.
The Mizuno JPX921 Forged irons have a significantly smaller sweet spot, making your margin for error on every hit even smaller.
Even though the sweet spot is a bit larger than other Forged iron sets in the market, it is still small enough to cause a less skilled golfer plenty of trouble.
The Mizuno JPX 921 Forged irons also have weaker lofts than the rest of the JPX 921 range. The long irons are about 2-3 degrees weaker than the Hot Metal iron set, however once you get into the short irons it is only one degree weaker.
If you’re accustomed to playing with game improvement irons that have strong lofts, you may find yourself losing some distance initially if you switch over to the Mizuno JPX 921 Forged irons.
However, this might only be temporary if you can learn to control your increased speeds and maximize your distance.
Stock Shaft and Grip
The stock shaft options for the Mizuno JPX921 Forged irons are the Nippon Modus 105 Regular and 12o Stiff.
Choosing the right shaft for your swing will have a huge impact on your performance. The biggest influence on your choice should be your swing speed.
If you have a swing speed that is <95 mph, it’s recommended to use a regular flex shaft. By using a regular flex you’ll be able to gain appropriate launch, spin, and speed for the best distance and accuracy.
Using a shaft that is too stiff for your swing will result in tons of shanks, poor ball flight, and less distance. So, if you have a slower swing speed than 95 mph, I’d highly suggest using the 105 Regular shaft.
On the other hand, if you have a faster swing speed that is >95 mph, you could try using the 120 Stiff. Since you have a swing speed faster than the average golfer, a stiff flex won’t have any harm on your performance.
In fact, you could still use a regular flex shaft if you’d prefer. Some pros still prefer to play regular flexes because it feels best to them and offers the best results. So, if you’re a fast swing speed player feel free to make the choice based on your personal preference.
When it comes to using a steel or graphite shaft, this is largely dependent on the feel you prefer. Neither one will result in substantial gains or losses, so picking a material depends on how you like the club to feel.
Just like the other Mizuno JPX 921 irons, the stock grip is the Lamkin ST Hybrid. The grip of a golf club doesn’t have a direct impact on your performance, however it may help you gain confidence.
Having a soft and comfortable grip will make you feel more confident when standing over the ball, helping you focus more on hitting the ball pure.
If you would like to use another shaft or grip you can always choose a different option, but it may cost you some extra money.
The clubs offered in the Mizuno JPX921 Forged iron set range from 4 iron-GW, with lofts differing from 21-50 degrees. The longer irons are spread out by 3 degrees, mid irons by 4 degrees, and scoring clubs by 5 degrees.
The Hot Metal and Hot Metal Pro irons are a degree stronger than most of the clubs, so the JPX921 Forged irons may have a little less distance on each hit.
A concern I’ve had with every Mizuno JPX 921 iron set is the distance gaps in the scoring clubs. The loft separation of 5 degrees will result in your distances with each club being farther apart, and this can cause multiple issues.
Instead of having a 7-12 yard difference in your 8 iron and 9 iron, you now have a 12-15 yard gap. This means that if you have around 150 yards into the green but hit your 9 iron ~145 and your 8 iron ~160, you’re left trying to figure out if you take a little off of your 8 iron or pump your 9 iron.
This may make it hard to find consistency, and could even cause less accuracy. However, do I think this is a major concern? Not really, and if anything it could simply increase your skill and ability with each iron.
Notably, Mizuno also offers a SW with 54 degrees of loft and a LW with 59 degrees of loft. Personally I wouldn’t purchase these and would choose to use premium wedge sets like Vokey or Jaws, but if you’re trying to save some money the JPX 921 wedges will still get the job done.
Who should use the Mizuno JPX 921 Forged irons?
The Mizuno JPX 921 Forged irons are not an easy club to hit, so I recommend only using them if you are a low handicap. The compact profile and shorter blade length makes these clubs very hard to use if you have an inconsistent swing.
However, if you are a more advanced player, this Forged iron will help you get the spin, control, and distance you’re seeking. As your handicap drops the execution of each shot is important, and these irons will help you with every hit.
Whether you’re needing to land the golf ball soft on the green or fade a shot around the tree, the Mizuno JPX921 Forged irons will provide the capability to carry out any shot.
If you are a high handicapper, then I highly suggest checking out a different iron set. The lack of forgiveness of the JPX921 Forged irons will show, and you’re shots will end up very inaccurate.
Instead, I suggest checking out the Mizuno JPX 921 Hot Metal irons. This iron set has tons of forgiveness as well as very strong lofts, so your shots will fly straighter and go farther.
Finding a good blend between game improvement and performance irons can be difficult, but the Mizuno JPX 921 Hot Metal Pro irons are a perfect fit.
These irons have the forgiveness of the Hot Metal iron set mixed with the blade length clubhead and control of the Forged iron or Tour model.
This will help keep the ball straight on the couple of mishits per round, but allows you to learn how to control your ball flight and add draw or fade.
If you’re a low handicap golfer but the Mizuno JPX921 Forged irons don’t seem like the right fit for you, then you could try out the JPX 921 Tour model. This iron set is similar to the Forged iron model, but they just have slightly higher lofts.
The Tour model was made with carbon steel rather than chromoly, so these irons will generate different spin and speed. Nonetheless, these irons were trusted by players on the PGA Tour to get the distance and accuracy they needed.
Similar to the JPX921 Forged irons, the Tour iron set will land the ball very soft on the green, helping you get the ball closer to the pin.
Mizuno irons have always been a prominent option for players of all skill levels. They have different clubs that provide specific needs for high and low handicap golfers alike.
These Mizuno JPX921 Forged irons are great if you are looking for a bladed iron set that will give you complete control over you shots. Just like other Mizuno irons, they will provide a soft feel at impact and an incredible sound as well.
