Are you thinking about switching to the Mizuno JPX 919 Hot Metal irons but aren’t sure if they’re the right clubs for you?
I’ve played Mizuno irons for a little over a year after getting professionally fit and have loved every second with them.
Over the years I’ve used all types of different irons but consistently find that Mizuno’s are some of my favorite in the market. They look amazing, feel amazing, and have helped me produce some quality shots since switching from Taylormade irons.
I’ve been a huge fan of the JPX 900 irons so I was excited to learn more about Mizuno’s most recent game improvement iron. Mizuno tends to put much more of their marketing and product development towards irons and wedges instead of woods and it shows here.
These game improvement irons are here to do just that, improve your game without some clunky design. While a good look is important, Mizuno also delivers the features to make them easy to hit for any player.
Here’s everything you should know about the Mizuno JPX 919 Hot Metal irons.
In my opinion, Mizuno has never gotten the credit they deserve. Brooks Koepka made them more popular when he used the Mizuno JPX 900 irons for his 2017 U.S. Open win (despite not having a contract). But overall, the brand has flown under the radar. Their clubs, well their irons and wedges to be specific, have an unbelievable and sleek design.
And a growing arsenal of choices. With a wide selection, from blades to the game improvement irons, there is a set of irons for every skill of golfer. Just because it’s not a household name like Titleist or Callaway, don’t let it stop you from checking out these irons.
The Mizuno JPX 919 Hot Metal irons are Mizuno’s most forgiving irons in the Mizuno collection. Mizuno’s goal with these irons was to create a larger sweet spot to make the ball fly higher than any previous version of irons to date.
When most golfers think of Mizuno they tend to think about a thin topline and more of a blade feel for advanced golfers. But the 919 Hot Metal irons are made to help more of the everyday golfers with additional distance and forgiveness.
The JPX 919 also has a tour version for very low handicappers and a forged iron set for more advanced players as well. If you’re a single digit handicap, the JPX 919 Hot Metal irons probably aren’t the clubs for you.
But if you’re looking for something that is forgiving and sexy to look at, these might just be your future irons.
The JPX 919 Hot Metal irons are a big upgrade from their former clubs, the JPX 900 irons. They lost any unnecessary design and replaced it with a beautiful, sleek cavity back. Unlike other game improvement irons, the JPX 919’s are sleek and to the point. No gimmicks here.
The Mizuno JPX 919 Hot Metal irons are different than any other iron in the Mizuno family. Instead of being cast, they are made with Chromoly 4140M. Like the other 919 models, the heel area of the cavity was opened to help with increased feel and move the weight from hosel toward the toe.
The weight redistribution should help most players create a higher launch angle and a steeper landing angle for more stopping power on the greens. This also helps improve the MOI (moment of inertia) and increased forgiveness, which is the #1 priority for game improvement irons. Here are some of the other features of the JPX 919’s:
These irons are not forged but instead made with Chromoly 4140M material. This is a highly resilient and durable material that allows for a new multi-thickness face. The result? Increased ball speed and better feel than ever before.
The JPX 919 Hot Metal irons also feel so good because of the re-engineered sound ribs which also makes them even more forgiving than before. As Mizuno said on their website, “Developed to hit specific vibration patterns identified as delivering a satisfying sensation through impact.”
While I love the sleek look of chrome irons, they get banged up quickly. The chrome plating of old has been replaced with a pearl brush finish that lasts longer and is much softer in the sun. Plus, this material is much less likely to rust if you don’t clean your clubs as regularly as you should.
Mizuno is all about helping you customize your clubs at no extra charge. You can choose custom shafts and grips at no up-charge for most selections which is a huge perk.
With all this, the 919 Hot Metals are a big upgrade from the 900 Hot Metals. Here’s straight from Mizuno on the 919 upgrades:
The irons also offer a steeper transition into more compact scoring irons and wedges. The standard set is a 4-iron through pitching wedge. This will make your 4-iron feel very different than your pitching wedge.
If you want, you can also upgrade to include with a set of matching sand and lob wedges (50, 55, & 60 degrees). The pitching wedge is 45 degrees so make sure to pair it accordingly to other wedges that you already love in your set. These are engineered from a softer X30 steel and blessed with precision-milled grooves and faces for improved spin and control around the greens.
I personally love these clubs. My experience hitting these clubs was terrific. Long, high, and forgiving. I’m not sure what more someone could want. Even though these are game improvement irons, there was feel and feedback on each strike (not something usually seen in this class of irons).
I scoured the reviews of the usual golf retailers on the internet and found that almost everyone reviewing was overwhelmingly positive about the JPX 919 Hot Metal irons.
This was my personal favorite review from a golfer on the Golf retailer TGW:
“I’ve played different forged irons for the past 6 years. And my first stroke with these irons I shouted “wow” on impact. The term “buttery soft” ain’t enough to describe the creamy feel when struck. The 919 Hot Metal irons forgiveness happens to be another big plus along with excellent distance. At least 1 club more distance. Softest clubs on the market!!!”
As I mentioned, Mizuno has three different versions of the JPX 919. If you’re a higher handicap player who is getting better, these are your best option for maximum distance and forgiveness. Lower handicaps, make sure to check out the Mizuno Tour 919 or the Mizuno forged irons instead. For more info, check out our full review of the Mizuno MP 18 irons.
In the realm of game improvement irons, here are three alternatives if you don’t think you’re quite ready for these Mizuno irons:
- Ping G400s: These irons have gotten positive reviews but in my opinion not nearly as advanced of a design as these Mizuno’s. Check out this comprehensive post on Ping G400s review to learn more.
- TaylorMade M4s: These are the most comparable to the Mizuno irons pairing forgiveness with a solid design. Learn more about the Taylormade M4s.
- Callaway Rogue Irons: These irons are by far the most forgiving and better suited if you’re just getting started. Callaway doesn’t have the sleek design of Mizuno but a lot more forgiveness as well. Check out our Callaway Rogue Irons review.
If you’re basing the clubs on looks alone I’d say hands down the Mizuno’s are the best looking of any game improvement iron. For the other clubs in this classification, you can look at our review of the best golf irons on the market. Please keep in mind though, the JPX 919 had not been released when the best iron review was written and as of this writing is our choice for best game improvement irons.
Update: Late 2019, Mizuno released it’s new lineup of MP 20 Irons. Included in this lineup is the MP 20 Hot Metal. While this iron serves a little more skilled golfer than the JPX 919 Hot Metal, head over here to check out our latest review of those irons.
As they are known as “game improvement irons” the 919 are Mizuno’s biggest size heads and most forgiving irons available. But let me be clear, these are not oversized “super game improvement irons” that you might find in clubs made for absolute beginners. They give you all the game improvement you need but still look like good player’s irons.
Unlike some of their tour models, graphite shafts are available for this set. They have the Project X, LZ and the Recoil 95 shafts as graphite options with no custom upgrade fee.
These clubs are much less likely to rust than previous models thanks to the upgraded material, Chromopoly 414. If cleaned on a regular basis you shouldn’t have to worry about rust.
The Mizuno JPX 919 Hot Metal irons provide a perfect balance of launch speed and distance for a higher handicap player. These JPX 919 Hot Metal irons are ideal for golfers who want it hit farther with high launch, combining all those distance benefits with a more classic Mizuno look. Plus, they’re by far the sleekest and gorgeous to look at in the game improvement iron sector.
This is a huge evolution from the previous Mizuno game improvement irons. With this addition, Mizuno now has a very thorough iron lineup that will help them gain more popularity among mid to higher handicap players.
If you’re looking for a new iron set to take your game to the next level, I’d seriously consider these Mizuno JPX 919 Hot Metal irons. This redesign not only makes them more forgiving with increased distance but also more sleek and beautiful as well. They are one of the best game improvement sets on the market.
