Mizuno launches new JPX919 Tour, Hot Metal and Forged irons
We knew Mizuno’s new JPX919 irons were coming soon when they popped up on the USGA Conforming Clubs list and GolfWRX Members were going crazy back in July. Our Two Guys Talking Golf podcast proceeded to dissect every millimeter of the photos. Then recently, Mizuno promised JPX919 irons on August 29 in a cryptic Tweet.
Now, all of the speculation is over. Mizuno has officially announced its new line of JPX919 clubs. The family consists of JPX919 Tour irons — the successors to the popular JPX-900 Tour irons that Brooks Koepka has now won three major with — JPX919 Forged irons, and JPX919 Hot Metal irons. The irons are now available through the Mizuno Performance Fitting System.
Each of the irons are designed with different metals and for different golfers. We have all of the information for you highlighted below, including photos of each of the irons.
In addition, we welcomed Chris Voshall, Mizuno’s Senior Club Engineer, back onto our Gear Dive podcast to get into the new JPX919 line. Listen to the full podcast on SoundCloud below, or click here to listen on iTunes!

JPX919 Tour irons
Mizuno’s JPX-900 Tour irons were initially designed with Brooks Koepka in mind, which is funny, because he’s now won three majors with those irons in the bag (2017 and 2018 U.S. Open, and 2018 PGA Championship). If you’re interested in hearing that full story, Voshall told it in-depth on our Gear Dive podcast.
The JPX919 Tour irons are the successors to those irons. They’re also Grain-Flow Forged from 1025E Pure Select Mild Carbon Steel for a soft feel, but the new versions are slightly smaller and more compact. According to Mizuno, the top edges have been narrowed by 10 percent compared to the JPX-900 Tour irons. Despite being made with a more compact shape, however, Mizuno says the irons offer “surprising stability for a compact players’ iron,” according to a press release.
That’s because the irons have a “stability frame” that maximizes weight distribution for off-center hits, and it also reinforces the topline and toe areas for sound/vibration dampening. The soles have also been made wider, but with more camber for enhanced playability, according to Mizuno.
They also have a zero-glare Pearl Brush finish.
The JPX919 Tour irons will be available in right-hand only, and will sell for $1,200 in an 8-piece set (3-PW), or $150 per club.
JPX919 Tour Specs
JPX919 Hot Metal irons
While the JPX919 Tour irons are made from 1025E, the JPX919 Hot metal irons are made from High Strength Chromoly 4140M. The new Hot Metals have multi-thickness faces for greater ball speeds, and one-piece face cups. Like the JPX919 Tour irons, the Hot Metal irons have a stability frame to enhance stability at impact, but they also have Sound Ribs that are designed to to “hit specific vibration patterns that ensure a satisfying sensation,” according to Mizuno.
“The most impressive thing about the JPX919 Hot Metal is the launch control and flight apex,” says Voshall. “The extra ball speed and distance doesn’t come from low-flying bullets – we work the design backwards from the correct landing angles. These are irons for the golf course, not just the launch monitor!”
Also, the JPX919 Hot Metals have set-matching gap, sand a lob wedges that are made from softer X30 steel; the wedges have precision milled grooves for greater spin control, as well.
These irons are available in both left-handed and right-handed, and they will for $1,000 in 8-piece sets (4-LW), or $125 per club.
JPX919 Hot Metal
JPX919 Forged irons
Mizuno’s JPX919 forged irons are made with a new engineering process; they’re “reverse milled,” meaning they’re CNC-milled from the sole up, thus creating a “larger area of minimum face thickness,” according to Mizuno. The result? The company’s “fastest ever one-piece forged irons in terms of measured ball speed.”
The JPX919 Forged irons are forged from 1025B mild carbon steel; Boron is infused into the steel, making it 30 percent stronger, according to Mizuno. The additional strength allows for a wider milling across the back of the face, according to Mizuno, which leads to greater energy transfer into the ball.
Mizuno’s JPX919-Forged irons will be available in both right-handed and left-handed. They will sell for $1,300 in an 8-piece set (4-GW), or for $163 per club.

Did Rory McIlroy inspire Shane Lowry’s putter switch?
Editor’s note: This is an excerpt from a piece our Andrew Tursky originally wrote for PGATour.com’s Equipment Report. Head over there for the full article.
The timing of Lowry’s putter changeup was curious: Was he just using a Spider putter because he was paired with McIlroy, who’s been using a Spider Tour X head throughout 2024? Was Lowry just being festive because it’s the Zurich Classic, and he wanted to match his teammate? Did McIlroy let Lowry try his putter, and he liked it so much he actually switched into it?
Well, as it turns out, McIlroy’s only influence was inspiring Lowry to make more putts.
When asked if McIlroy had an influence on the putter switch, Lowry had this to say: “No, it’s actually a different putter than what he uses. Maybe there was more pressure there because I needed to hole some more putts if we wanted to win,” he said with a laugh.
To Lowry’s point, McIlroy plays the Tour X model, whereas Lowry switched into the Tour Z model, which has a sleeker shape in comparison, and the two sole weights of the club are more towards the face.
Lowry’s Spider Tour Z has a white True Path Alignment channel on the crown of his putter, which is reminiscent of Lowry’s former 2-ball designs, thus helping to provide a comfort factor despite the departure from his norm. Instead of a double-bend hosel, which Lowry used in his 2-ball putters, his new Spider Tour Z is designed with a short slant neck.
“I’ve been struggling on the greens, and I just needed something with a fresh look,” Lowry told GolfWRX.com on Wednesday at the 2024 Wells Fargo Championship. “It has a different neck on it, as well, so it moves a bit differently, but it’s similar. It has a white line on the back of it [like my 2-ball], and it’s a mallet style. So it’s not too drastic of a change.
“I just picked it up on the putting green and I liked the look of it, so I was like, ‘Let’s give it a go.’”

“…the irons have a “stability frame” that maximizes weight distribution for off-center hits, and it also reinforces the topline and toe areas for sound/vibration dampening.”
This is exactly the weight distribution on the PING ZING iron design.

If Miz had put a high density tungsten plug low in the toe to displace the lower density steel, the hollow cavity would be larger and more forgiving… believe it
Pr
Aug 31, 2018 at 11:24 am
I dunno………. that cavity has been stretched so far into the hosel it looks weird………… is that even safe? I’d have to look at it in person to see what would happen in the loft-lie machine when I go to bend it…………

Sep 4, 2018 at 9:55 am
No definitely not safe. Mizuno definitely did not test and retest these irons. They just pressed some out, attached them to shafts and will keep their fingers crossed.

I don’t understand how and why companies are still trying to tout distance and jack lofts stronger which are much harder to hit for the average player. You then have a ridiculous 5-6 degree gap on scoring clubs and a tight spread on 4-5-6- thus eliminating those clubs as hittable for most mid handicappers. So they end up with 3-4 usable clubs per set (7-PW) with 15 yard distance gaps between them and that would be for someone who can hit it solid. Couple with that shoddy ball striking and you have sets that are basically worthless for non single digit players. You can either advertise distance or playability but not both. a 20* 4 iron on the hotmetal is hilarious. Just stop. Someone has to lead, and sadly even Titleist and Mizuno caved in. Caveman golf.

Absolutely spot on, well said
chance
Sep 4, 2018 at 1:05 am
Completely agree. I think people just want to be able to say they hit their 7 iron 190 yards. Rather sad that we’re in this odd phase of equipment coupled with distance hype marketing.
~j~
Sep 7, 2018 at 9:37 am
Yup. Got a budy who went with the new M3 irons, claims now he hits his irons the same distances I do with my weaker-lofted Mizzys. Doesn’t seem to get it though when I tell him his lofts are all 3-4* stronger per club than mine.
In all fairness he does hit them better, more accurate, than his former set. I’d rather have better accuracy and feel than a few extra yards though anyday.

That badge on the Forged head looks like it was stuck on by my 5-year-old grandson. Macaroni art-worthy. Also, no Tour model for left-handers? Again?? You’re driving me to Srixon…
Andrew
Aug 30, 2018 at 7:36 pm
Totally agree – so frustrating!! I would try/get those tours in a heartbeat if offered in left hand. I will look at the forged but it is frustrating. I’m old enougth to remember when the TP9 was the only ‘players’ club Mizuno had available to lefties (and of course i wanted the TP19!)

Steve
Oct 8, 2018 at 1:32 pm
Mizuno is in the business of turning a profit. There aren’t enough sets sold to justify the costs of molds and manufacturing. They aren’t Callaway.
While I sympathize with LH golfers, it’s not a conspiracy. It’s about staying in business.

Aug 29, 2018 at 12:56 pm
Love my now decade-old Mizzy’s, but I echo my fellow left-handers in expressing my disappointment and frustration with Mizuno that the Tour’s are again not available to me. I love the way they’ve preserved a classic look while keeping up with technology, but I feel Mizuno is a bit backward and willingly blind in not offering all models in left hand version.
TwoLegsMcManus
Aug 29, 2018 at 6:29 pm
“a bit backward and willingly blind”
As someone who fits many, many minority categories *as a consumer*, I empathize with the plight of lefties.
Mizuno is simply a capitalist company behaving with modern capitalist guidelines. Ask any MBA.
Left handers are 10% of the population, presumably the same % of golfers.
If a company makes an iron that appeals to ~10% of its market (anything like the Tour falls into this category), potential LH sales are such a small percentage that it’s likely a loss.
There was a time when companies would allow loss in some areas – to keep the minority customers – and “make it back” with their best sellers (plus maybe bags, caps, etc).
Modern capitalism dictates that any “flavor” that’s 10% isn’t worth making at all. Big sellers only, big box, one size fits all. All lefties can play the single left-handed model we offer. OR, pay an enormous premium for something truly “custom”.
(Under socialism, workers control production, you could guarantee left-handed everything.)
Eric
Aug 30, 2018 at 3:36 pm
That’s an interesting point…im actually a lefty as is my father, and we both play right handed. If we’re not completely unusual in doing so, and I don’t believe we are, my guess is the actual percentage of lefty golfers might be even lower, like closer to 5%.

Great looking irons, but look at the pictures of that insert on the back. see the corner of badge sticking up like it almost doesn’t fit? Just like some of the Ping irons the badges catch dirt along with the look is like you slapped some lead tape on the back of your iron or maybe you like that 1950’s look.

I stopped reading at “right-hand only.” Mizuno apparently doesnt want to build a club for me. I have the 900 Forged now and I like them, but much prefer the look of the Tour version and was hoping this version would be available.
I’m not mad, just disappointed.
