When you intend to change irons, you’ll surely get confused while picking the best golf set. Although there are many options with forgiving or improving features on the market, not all of them would sound okay. These days, pro golfers often suggest professional starters choose between Srixon’s ZX5 iron and Mizuno’s JPX 921 iron.
From our findings, we believe the Srixon ZX5 iron to be superior to the Mizuno JPX 921 iron because the model would reduce vibration to produce precise power shots. But if you need improvement in your skills, JPX 921 is the only option with the required amount of support.
However, my opinions can’t be correct for everyone. For this reason, we’ve figured it’d be good to show the side-by-side comparison and let you decide which one suits your playing style the most.
Overview of the Srixon ZX5 iron
The Srixon ZX5 is a cavity-back iron. So, this is supposed to be much more forgiving than any other professional club in the market.
People would find it easy to adapt within a few overs. The construction suits most mid and beginner-level players.
One special thing we’ve noticed about this ZX series is the sole of the blades. The V shape of soles helps to regulate pressure and power. But this shape is actually for better turf interaction.
Overview of Mizuno JPX 921 iron
Mizuno JPX 921 is a great choice for mid-capers and is very comfy for most golfers. It features both forgiveness and game improvement together.
we’ve been recently using this model but still, the average scoring didn’t drop too much. It’s far different from other Tour Series irons.
The club has become shorter and is a bit of an extra hitting zone on the core design. Also, this model is a few centimeters thinner than other Japanese iron sets.

What are the Differences Between Srixon ZX5 and Mizuno JPX 921 Irons?
When your game’s tomorrow, you don’t have much time to think deeply to find differences between them. So, we are pointing out the notable differences between ZX5 and JPX 921 below.
The Srixon ZX5 has a thicker and wider hitting zone. It helps to generate power. The special thing about this model is the V-shaped sole that interacts with the turf pretty well. 9/10 swings would surely hit the ball and send it to a distance using this iron.
whereas the Mizuno JPX 921 has a shorter hitting zone. And the bottom of this iron has some added weight so that the glide becomes perfect.
Except that, you can’t be always accurate with the thinner and narrower hitting area. Preciseness from the player is required to score with this iron.
So, you can say that ZX5 is more forgiving than JPX 921. Mizuno compromises forgiveness to let players improve in the game.
In the Srixon ZX5, you can find the V toe having Tungsten integrated. It stabilizes the construction when too much power is being surpassed through the bat. It’s really helpful for those models that are not forged.
Because of not having enough stopping power, many might think Mizuno irons aren’t fully stable. But in reality, the bottom points can bring together the whole construction weight against gravity to help users swing with balance.
It’s more of a pro feature that beginners may not understand by using a very forgiving iron. Both models can be stable in their own ways.
The ZX5 construction seems more stable because it helps to make shots straight because of the forgiving nature, and thus, the unique bottom handles the stability well.
The Srixon ZX5 comes with Golf Pride Tour Velvet 360. This one is for optimal feel on hands to play with the iron consistently. It has a thick texture and features firm gripping. The butt of the grip is also thinner than some other common grips on the market.
On the contrary, MCC Plus 4 is the stock grip of Mizuno JPX 921. It generates power with the help of thick layers. It can’t give the full comfortable feel to the users. But MCC Plus 4 can do everything to make the iron stick in the player’s hands.
|Factors||Pride Velvet 360||MCC Plus 4|
|Texture||Standard for every player||Extended texture for added stability|
|Feel||Soft and responsive||Soft but micro-textures make extra traction|
|Butt||.580 normal butt||.600 extended butt|
|Feedback||Featuring gentle feedback to increase the game enjoyment||Eliminates iron reaction after every hit|
|Layers||Single layer for firm gripping and hard hitting||4 layers to multiply power from soft holds|
although you can change the stock grip anytime you want. But still, JPX 921 with MCC Plus 4 makes a great combo for enhanced performance.
Nowadays, most golf irons come with at least a minimal range of offset. It’s time to compare the offset ranges between the two irons.
|Club Head||Srixon ZX5||Mizuno JPX 921|
|4 iron||4 mm||3.8 mm|
|5 iron||3.8 mm||3.6 mm|
|6 iron||3.5 mm||3.4 mm|
ZX5 has a higher offset amount than JPX 921. It means you can loft the ball higher in the sky with any ZX5 iron. Mizuno JPX series has less but moderate offset to prevent ball slicing mainly. It is only to make the shots speedier rather than lofty.
Lie and Loft
The Srixon ZX5 is a good choice for standard and upright lie-angle users. The lie angle here is not less than the ideal lie angle.
If your body alignment requires a higher lie angle, you should choose ZX5. But keep in mind that the loft is lower than average here.
The Mizuno JPX 921 is more of a flat lie type. It is almost the standard lie you can expect to see. With that, it also has a below-average loft range like the ZX5. The lower loft angle is to provide longer shots in matches.
Let’s see a chart of the average loft with the lofts of the two irons.
|Golf Club||Loft range||ZX5||JPX 921|
You can see both irons having 0.5º extra to prevent ball slicing and produce longer deliveries. And the ZX5 is more upright comparatively. That’s why we’re suggesting JPX 921 for flat anglers.
