The Mizuno JPX923 Forged irons are a perfect bridge set for players moving into or out of Tour-style irons. Good forgiveness and very strong ball speed. Traditional look at address and thinner soles.
Mizuno’s JPX923 iron family covers a lot of ground. On one side, it offers Mizuno’s maximum forgiveness in the Hot Metal [review HERE] and the new Hot Metal HL [review HERE]. On the other end is Mizuno’s most-played professional iron, the JPX923 Tour. The JPX923 Forged irons are the bridge. If you’re ready to step up from Hot Metal but still want distance and forgiveness, these are for you.
That bridge quality of the JPX923 Forged irons comes through from the first time you look at them. There are some shiny chrome elements that nod to the Hot Metal side, but the dimensions lead toward Tour. With the exception of the “JPX,” everything is silver or white which creates an ultra-clean look. The White-Satin Brush finish looks stellar.
At address, the JPX923 Forged irons are safely in the players category, toward the thicker side. They share their minimal offset specs with the JPX923 Hot Metal Pro [review HERE], but are otherwise smaller in every way – blade length, top line, and sole width. For this iteration, Mizuno focused on making the 7-GW more compact, which enhances their appeal for better players.
Finally, I’ll offer a comparison to the JPX923 Tour [review HERE] for those thinking about taking that final step. Above you see the JPX923 Forged (left) and the JPX923 Tour (right). The most standout difference, to my eye, is the thicker top line of the Forged – 1.5mm-2mm thicker throughout the set. There is markedly more offset in the Forged long irons, but the difference shrinks to nothing as you get to the PW. Additionally, the Forged has a longer blade length (between 1.5mm and 4mm) and a wider sole (1mm to just over 2mm). Overall, I would say that there’s a noticeable difference when they’re side by side, but the JPX923 Forged holds its own as a good looking players iron.
Sound & Feel
The sound and feel of the JPX923 Forged irons is a substantial upgrade over the previous version [review HERE]. Impact is slightly below average in volume, creating a low-pitched “tock.” The sound is traditional but with a hint of explosiveness nodding to the distance it can produce. Through your hands, you’ll get a sensation that aligns with the sound: medium-soft and conventional with just a hint of pop.
Additionally, I was impressed with the level of feedback provided by these irons. Even small misses can be felt in the hands. These clubs are particularly expressive on thin strikes. Hitting a shot even slightly low on the face can be felt and heard clearly.
The JPX923 Forged irons are, in a way, a combo set. The 8-GW are made of 1025 Pure Select Mild Carbon Steel, just like the JPX923 Tour. However, the 4-7 irons are made from Chromoly like the Hot Metal irons. To me, the feel is consistent throughout the set, despite this material difference. The one thing I did note is that the long irons are slightly louder than the scoring irons.
Picking up the bridge theme again, the Mizuno JPX923 Forged irons have a loft structure that falls between the JPX923 Tour and JPX923 Hot Metal Pro. They are 2-3 degrees stronger than the Tour and 1.5-2 degrees weaker than the HMP. This results in launch angles that are strong, more akin to the Hot Metal irons, but spin that’s closer to the Tour.
Where the JPX923 Forged irons are unquestionably more like the Hot Metal irons is in the ball speed department. Throughout the set, their top end speed is elite. You could certainly categorize these irons as “players distance,” as they will keep up with anything in that space.
When it comes to forgiveness, the JPX923 Forged sit right between the HMP and Tour. Comparing the Forged and Tour on the launch monitor, it’s easy to see that the Forged produces more consistent ball speed and distance. You can lose a few yards on a mishit, but you’ll have a makable up-and-down chance. This forgiveness is particularly noteworthy in the 4I which launches and spin consistently, even on fairly ugly swings. Comparing the Forged to the HMP, I would rate the difference as measurable but not obvious.
Finally, going back to the mixed makeup of this set, something I’m always sure to test is how smoothly the set performs on either side of the divide. Mizuno has done an excellent job positioning the CG to ensure that there’s a sensible gap from the 7I to the 8I. Nothing in the launch monitors numbers would indicate that they’re made of different materials.
In their product description, Mizuno states that the JPX923 Forged irons are for “Pro to Mid Handicap” golfers. While that seems overly ambitious, these irons are capable of backing it up. For a highly skilled player who doesn’t need to feed their ego, there’s no reason not to take the speed and forgiveness available here. On the other side, a mid handicap golfer can play these without being punished for every mistake. Get these fit with the right shaft and specs, and you’ll have a set you can enjoy for many seasons.
