Test Review: MIZUNO JPX 925 FORGED Irons

Today, I had the chance to test out a brand-new set of golf irons.
The test club was the MIZUNO JPX 925 FORGED 7-iron.

It was paired with the N.S.PRO 950GH neo shaft.
The specs are as follows: 30° loft, 37.25 inches in length, S flex, 98g shaft weight, 1.7 torque, D0 balance, and a butt-end kick point. The total club weight is 418g.

This is a sleek forged iron from Mizuno.
While Mizuno’s MP line often comes to mind first when talking about irons, the JPX series has also long been popular—and rightly so.
The JPX line is arguably more forgiving than the MP, but it doesn’t compromise on looks or quality.
If you prefer a classic, traditional feel, go for MP. But if you’re looking for more forgiveness and distance with modern technology, JPX might be your go-to.

It’s simple and stylish—exactly what you’d expect from Mizuno.
Looking closely, it’s evident that this is a shallow-faced iron.
Personally, I prefer higher-face irons for better compression, but many golfers out there love this shallow look. Especially those who swing level through the ball might find this shape more appealing.

The back face looks like it has an attached part.
I tend to prefer irons made from a single solid piece, but many golfers enjoy this multi-material, “composite” structure.
Each design delivers a unique feel. For me, the presence or absence of hollow cavities is more important than material mix. I’ve always preferred solid, non-hollow constructions.

The bulging shape made me wonder if this was a hollow-body iron, but it might not be.
The shape is clean and smooth—not sharply contoured, but rather round and soft, giving off a sense of forgiveness.
Despite its easygoing design, it doesn’t feel cheap. The overall finish is excellent.

Looking at the depth of the cavity, it appears to be a half-cavity at first glance. However, if you were to remove the back insert, it could very well reveal a full cavity structure.

The top line seems a bit thick but still within what I would consider the standard range.

The sole is fairly standard in width, and you can clearly see that a lot of material has been ground off for better turf interaction.


The leading edge is aggressively ground down, which is increasingly common in modern irons.

The trailing edge has also been significantly shaved down, further optimizing turf performance.

The neck length is standard—nothing out of the ordinary.

The hosel is engraved with “GF FORGED HD CHROMOLY 925”.
Mizuno is well known for its meticulous forging techniques and materials, and this iron is no exception.

The face doesn’t have any milling patterns.
Mizuno has traditionally used smooth face finishes for their irons.
While many modern irons feature face milling, Mizuno’s choice to go without may suggest it’s not as essential as some think.
Personally, I don’t find milling completely pointless, but I have yet to find one that truly reduces flyers the way I’d like.

The installed grip features the Mizuno logo and looks sharp.
Rather than being soft, it feels tacky and secure in the hands, which should work well even in wet conditions.

Practice swings felt decent overall.
Since it’s a lightweight model, I took extra time to get a feel for it during warm-up.

When I addressed the ball, I was a bit disappointed.
It wasn’t hard to set up to, but it didn’t have that “beautiful face” either.
The rounded design was just too prominent for my taste—I expected something sharper and sleeker, especially from Mizuno.
Perhaps this is just the JPX look? Are most recent JPX irons designed like this?
It’s been a while since I tested Mizuno irons, but honestly, this one looked a bit cheap, which was disappointing.

Now on to the actual hitting session.
The feel at impact was… just okay.
There was a certain “disconnect” between materials, or perhaps a slight hollow feeling.
Ball contact wasn’t particularly satisfying—the ball seemed to jump off the face quickly.
There was a noticeable gap between what I expected from the looks and the actual feel at impact.
This isn’t the plush forged feel I had hoped for, but honestly, that’s becoming more common these days.
Maybe my expectations for Mizuno irons were simply too high.

In terms of launch, it was average.
The iron didn’t feel overly demanding, and thanks to the well-designed sole, it seemed like it wouldn’t dig too much during real rounds.

Stability was quite impressive.
While it may look like a half-cavity, the actual forgiveness is more on par with a full cavity.
Many players will appreciate this level of playability.

Workability was also solid.
It was easy to shape shots both left and right.
The ball flight was quick off the face, giving it a “get it done fast” feel compared to traditional forged irons, with reduced hold time and tighter curves.
It’s a neutral and responsive club, reacting equally well to draws and fades.

As for distance performance—very strong.
The ball popped off the face with good speed and power.
That said, irons aren’t meant to chase distance like drivers. They’re for precision and control.
In my opinion, slower ball speeds often allow for better distance control, but many modern irons go in the opposite direction.
With this club’s strong face rebound, you’ll need to develop feel to dial in distance, which could be challenging for some.
Given the elegant look, I expected this to be a feel-focused iron, but it turned out to be a distance-oriented model that definitely packs a punch.
In today’s game, even irons are expected to produce more distance, and this one should be quite popular because of that.

One thing that hasn’t changed—Mizuno’s build quality is still top-notch.

This club feels like a modern classic.
Mizuno sticks to a clear design philosophy, and every evolution builds logically from that foundation.

Mizuno irons have always been exceptional, but many brands today have caught up—raising the overall standard of the market.

Still, I hope Mizuno continues to lead by example—staying true to its roots with unmatched craftsmanship and technicalexcellence.

Even though it’s packed with modern tech, the design doesn’t scream “high-tech”—a true testament to Mizuno’s refined aesthetic sense.

It was a meaningful and enjoyable experience to revisit Mizuno irons after such a long time.

Mizuno JPX 925 Forged Iron: Complete Review and Buying Guide
The Mizuno JPX 925 Forged Iron represents what the manufacturer describes as “the most dramatic performance enhancement in the history of the JPX Forged line.” This revolutionary iron combines cutting-edge technology with Mizuno’s legendary forging craftsmanship to create what many consider the ultimate player’s distance iron. Built for golfers who demand precision, feel, and distance, the JPX 925 Forged delivers on all fronts while maintaining the iconic buttery feel that has made Mizuno synonymous with forged iron excellence.
Key Features and Technology
Grain Flow Forged HD Construction
The JPX 925 Forged utilizes Mizuno’s advanced Grain Flow Forged HD process, which creates a multi-material construction designed to optimize performance across the entire set. The long irons (4-7) feature a forged Chromoly 4120 face and neck paired with a 431 stainless steel back, allowing for maximum CORTECH design flexibility and greater control over center of gravity depth. This dual-material approach provides enhanced ball speed and launch characteristics while maintaining the workability expected from a forged iron.
Material Composition by Club
The engineering philosophy behind the JPX 925 Forged becomes evident in its material selection. The shorter irons (8-GW) are forged from 1025E Pure Select Mild Carbon Steel, ensuring precision, control, and that iconic buttery feel Mizuno is renowned for. This material choice provides superior feedback and control for approach shots and scoring clubs, where precision takes precedence over pure distance.
Triple Cut Sole Technology
The Triple Cut Sole is meticulously engineered to enhance turf interaction, providing players with greater versatility and playability across varying lies and conditions. This sole design reduces turf drag while maintaining stability through impact, making the club more forgiving on less-than-perfect strikes while preserving the shot-shaping capabilities that better players demand.
Technical Specifications
Loft and Lie Specifications
The JPX 925 Forged features a carefully calibrated loft matrix that balances distance with playability:
- 4-iron: 21° loft, 60.5° lie angle, 0.15″ offset, 38.75″ length
- 5-iron: 24° loft, 61° lie angle, 0.142″ offset, 38.25″ length
- 6-iron: 27° loft, 61.5° lie angle, 0.134″ offset, 37.75″ length
- 7-iron: 30° loft, 62° lie angle, 0.126″ offset, 37.25″ length
- 8-iron: 34° loft, 62.5° lie angle, 0.118″ offset, 36.75″ length
- 9-iron: 38° loft, 63° lie angle, 0.11″ offset, 36.25″ length
- PW: 43° loft, 63.5° lie angle, 0.102″ offset, 35.75″ length
- GW: 48° loft, 64° lie angle, 0.091″ offset, 35.5″ length
Design Philosophy
The loft matrix features a 30-degree 7-iron, which positions it in the players-distance category without being overly aggressive. Mizuno has strategically weakened the lofts on the 9-iron, pitching wedge, and gap wedge to improve gapping and ensure smooth transitions throughout the set. This approach prevents the distance gaps that can occur with overly strong lofts in the scoring clubs.
