The JPX 919 Forged is Mizuno's most versatile iron. In the hands of a tour player searching for a distance equalizer, or an amateur wanting feedback to evolve their game. The streamlined JPX 919 Forged delivers on every level. Get the Mizuno JPX 919 Forged Irons custom fit or standard, with free shipping from Just Say Golf. It should go without saying that Mizuno hopes to continue its tour momentum with the 919. The 919 is the first JPX series to leverage Mizuno’s enhanced Grain Flow Forged HD process, which as we’ve covered a few times now, limits the amount of excess material that spills out of the lower part of the mold during forging.
We’re rolling towards the end of summer, and while that’s less than awesome, the upside is it means we’re rolling closer to the next release of Mizuno JPX irons.
Speaking as a guy bound by embargo to pretend to know less than I do, I’m finding it hard to contain my excitement. Unfortunately, Mizuno likely won’t have much to say until late August, which means we won’t have much to say until late August.
For now, we’re limited to what we can ascertain from USGA photographs.
As you glance through the pics, it’s worth remembering that JPX is Mizuno’s Modern technology line. That means modern shaping, straight edges, and different materials. The 919 Forged is Grain Flow Forged from 1025 Boron, while the 919 Hot Metal is cast from Chromoly Steel. There’s also a replacement for the JPX Tour which will end its production run having been in the bag for consecutive U.S. Open victories.
Will Mizuno add a 4th iron to the JPX lineup? I’m not ruling it out.

Mizuno Pro 719
The Mizuno Pro line is currently exclusive to Japan. While there may be some material differences (the 719 features a copper underlay for softer feel), the iron is otherwise identical to the JPX 919 Forged, which means we get a little more glamorous early look than the USGA gives us.

With concessions for the fact that the USGA’s priority is documentation and not making the product look its best, what do you think of what you’ve seen so far? Are you looking forward to the new JPX 919 lineup?

What we say...
Mizuno's latest JPX919 Forged Irons are the company's most versatile and fastest forged iron yet
The big golf brands reckon ultimate endorsement comes from tour players using their products without being paid. Especially if they’re a big name who’s winning big events.
When Brooks Koepka won the 2017 US Open with a set of Mizuno JPX900 Tour irons – and no contract – the Japanese company was obviously delighted. When he defended his title this year and captured the US PGA Championship, with the same irons, it was the icing on the cake.
The JPX range has been a huge success on tour and in pro shops, but it’s two years old now – so they’re being replaced by, in our view, some of the best-looking irons Mizuno has evermade. They’re called JPX919, and this is what you need to know about them…
The 919 Forged has a tough act to follow – Mizuno say its predecessor (the JPX900 Forged, used by Nick Faldo) was their biggest-selling forged iron... ever. Like the Tour it has HD forging, which improves feel for shots hit low in the blade, which wasn’t in the original.
Mizuno’s engineers have developed a clever reverse-milling technique (going through the sole) which allows them to thin down the face to maximise ball speeds from a larger area. Like the Tour there’s an “open heel” which Mizuno say lets vibration waves out, to further improve feel and feedback. There’s also an extra degree of loft on each of the 4, 5 and 6 irons as players believed the original 900’s landing angles were quite shallow.
Mizuno JPX 919 Forged Review: First hit
We’ve seen some Mizuno irons in our time, but putting all three new JPX919 models together with the current MP18s (three irons) has to be the best iron line-up Mizuno have ever produced. The 919 Forged is gorgeous. It has a slightly larger head and decent sized cavity which inspires confidence, while a small amount of offset keeps a clean, inviting look at address. The data (below) stacks up behind everything Mizuno says, too.
Key numbers: How do they compare to JPX919 Tour and Hot Metal?
What Mizuno say:
A new reverse-milled clubface, CNC-milled from the sole up creates a larger area of minimum face thickness, making the streamlined JPX919 Forged Mizuno’s fastest ever forged iron. The weight removed from the face allows a lower, deeper centre of gravity making it easier to flight long and mid-irons. Mizuno’s trademark workability and elevated Grain Flow Forged HD feedback ensure the JPX919 Forged is also Mizuno’s most versatile iron.
Like the JPX919 Tour and JPX919 Hot Metal the JPX919 Forged features a durable Pearl Brush finish and stability frame, open at the heel to enhance stability, launch and loft-appropriate flight apex for soft-landing approaches. The Forged model is Grain Flow Forged HD (High Density) from a single billet of 1025B mild carbon steel in Hiroshima Japan for unmistakable Mizuno feel, with a trace of Boron infused into the billet to make it 30% stronger and allow greater design possibilities in a forged head. The overall package is one of “balanced performance” with the JPX919 Forged offering the ultimate blend of ball speed, stability and feedback within a more refined playing profile.
“A deeper, wider milling across the back of the face allows the JPX919 Forged to transfer more energy to the ball than any previous Grain Flow Forged iron,” says David Llewellyn, Director of Golf R&D at Mizuno. “None of that would have been possible without that small addition of Boron into our steel billets, which gives that additional strength needed to reinforce the face.”
