What are the features?
Unlike the JPX919 Hot Metal irons, which are cast, the JPX919 Forged irons are forged, hence the name.
They are meant to deliver on every level. Here are many of the features:
The iron is made of 1025 Boron, which is 30% stronger than normal steel. This allows the face to be made thinner for faster ball speeds.
Back/Reverse Milled Face
The JPX919 Forged is CNC milled from top to bottom. The area of minimum face thickness is larger, which improves ball speeds across the face.
The weight savings afforded by the construction of the iron allow the center of gravity (CG) to be placed low and deep. This results in an easier launch and more workability in the mid and long irons.
Like in the JPX919 Hot Metal, the heel portion is open. This enhances the stability and launch and also produces a tour-caliber vibration and sound.
Grain Flow Forged HD
The JPX919 Forged irons were built through the Grain Flow Forging Process, patented by Mizuno in 1998.
This process involves several precise steps, starting with a billet of 1025E mild carbon steel. The result is a feel, consistency and durability unique to Mizuno.
There are many set configurations to choose from: full, split or short. The available stock set makeup is the 4-GW.
The stock shaft options are the Dynamic Gold 105 R300 and S300, both in steel.
If you’re interested, full information on shafts, grips, their specs, and the Mizuno Custom Program can be found on the Mizuno website.

How do these irons perform?
In comparison with the JPX919 Hot Metal irons, the JPX919 Forged aren’t quite as long. This wasn’t at all surprising to learn.
It’s partly because of the slightly weaker lofts, and also, the JPX919 Forged wasn’t meant to be a pure distance iron.
With that said, the JPX919 Forged irons are still, on average, longer than your typical players iron, which is cool.
I just don’t think that raw distance is important in irons, particularly in the scoring irons, so I don’t have much to complain about here.
Because the JPX919 Forged irons are between GI and better-player on the skill spectrum, you would think that forgiveness might be poor to non-existent.
Actually, the forgiveness of these irons is surprisingly good. It’s a little worse than the Hot Metal variant, but considerably better than the Tour variant. The increased area of minimum face thickness certainly contributes to this.
It means that when you make lousy contact, the results aren’t usually going to be disastrous, and you’ll often still hit the green.
If you want some forgiveness but not too much, the JPX919 Forged irons are the perfect fit.
The JPX919 Forged irons really shine here.
Overall, I found ball flights to be very consistent and highly controllable. Capable golfers should have no trouble shaping their shots.
During my testing, I was easily able to dial in my short irons and hit precision shots into the green. At the same time, I found the long irons easy to get up in the air.
On another note, the sole grind is slightly altered from the previous JPX900, and as a result, the turf interaction is improved.
When you hit these irons solidly, you’re going to be handsomely rewarded.
What about look, sound & feel?
The JPX919 Forged irons have a premium, classic look. It’s a traditional look with no coloured paint fill.
The design on the back looks really precise and sharp; I think it’s fantastic.
I should mention that although the bottom surface on the back of the iron looks black in the stock image, it’s actually silver. As with the rest of the irons in the JPX919 line, the head is all silver with a high-quality chrome finish.
The thickness of the top line is about the same as (maybe even a bit less than) the JPX900 Forged iron, but the edges look cleaner and the finish looks better in my opinion.
The Sound & Feel
We expect feel to be good in a forged iron. The JPX919 Forged mostly doesn’t disappoint in this regard.
At impact, the feel is quite firm and the sound is a bit muted, but there is also an element of explosiveness there, which is nice. It’s clearly different than the clicky sound and feel of the Hot Metal irons.
Feedback with the JPX919 Forged irons is pretty clear. It’s not as distinct as the JPX919 Tour model, but it’s enough to be able to tell if it was a mis-hit or pure strike.
I would say that the sound and feel are improved over the previous JPX900 Forged irons. At the end of the day, this is a win for Mizuno and consumers.
Where should you buy these irons online?
At the time of writing, you can pick up a set of JPX919 Forged irons on the official Mizuno website here.
You can choose your hand and shaft, but it seems that there’s only one choice for set makeup at the moment. I suggest contacting Mizuno to see if there’s anything you can customize further.
eBay is a fantastic source for new and used sets, and you’re pretty much always going to find listings there.
The Mizuno JPX919 Forged irons are excellent irons overall. They give you a bit of everything: excellent distance, some forgiveness, workability, a traditional look, and a premium feel and sound.
They’re in between game-improvement and better-player irons, and I would recommend them for high, mid or low handicappers who want to bring forged performance to the course.
If you’re looking for a forged iron, definitely give these a try.
