Ping G430 Vs Mizuno JPX923 Hot Metal Irons Comparison Overview

Ping G430 Vs Mizuno JPX923 Hot Metal Irons

It seems that every golf club manufacturer is trying to corner the game improvement iron market.

This is good news for players as it means more options and more competitive pricing. However, it can also make choosing the right irons more difficult.

Adding to the complexity is the fact that a lot of manufacturers are using different technologies to elevate game improvement iron performance.

Such is the case with the Pong G430 and Mizuno JPX923 Hot Metal irons. We wanted to see how the different GI technologies compare and give you an insight into the overall performance of these sets.

Ping G430 Irons Overview

“One of the most unique features of the Ping G430 irons is the shortened hosel which works to lower the CG of the irons.”

This had a very interesting and noticeable effect for our testers. For one thing, they mentioned that the long G430 irons were very comfortable to swing.

For another, most of our testers were noticing increases in their average ball speeds.

While club head speed remained the same for our testers, their ball speeds were increasing.

We chalked this increase up to the lower CG which seemed to be allowing our testers to put more force behind the ball without affecting club head speed one way or another.

The forgiveness technology was pretty average though. You get perimeter weighting and a special badge construction that smooths out the feel – effective but nothing new.

Mizuno JPX923 Hot Metal Irons Overview

“Like the G430 irons, the Mizuno JPX923 Hot Metal irons have compact blades.”

However, the Mizuno JPX923 Hot Metal’s don’t use shorter hosels to help increase distance; they use an extremely thin face construction instead.

It was noticeable to almost all of our testers that the Mizuno JPX923 Hot Metal irons played hotter than the Ping G430 irons.

The distance increase was almost negligible though. The average distance for our testers with the Mizuno JPX923 Hot Metal 5-iron was 164.5 yards compared to 162.2 yards with the G430 5-iron.

Mizuno also decided to emphasize short game spin with these irons which may or may not be a huge point of emphasis for the player seeking GI irons.

“The thinner face construction and premium materials (chiefly, chromoly) ultimately made the Mizuno JPX923 Hot Metal irons better GI irons. However, you shouldn’t sleep on the Ping G430’s if you like a low CG.”

Ping G430 Irons First Impressions

The first thing to notic about the G430’s is the size. These are large game improvement irons with thick soles, built for distance and forgivness.

The shorter hosel stands out too, with the offset of the club. It helps to lower CG and get the ball flying higher.

There’s a bit of color on the back too with the Purflex cavity badge. This dampens vibrations on mishits and it houses 7 striking zones which produce straight and high shots even when you don’t connect flush.

The visible screw in the toe stands out too. There is another weight in the hosel tip and this increases MOI across the face. These irons will fly high and straight even when you don’t connect flush.

The other thing that stands out is the lower lofts, the main reason for the distance. With that being said the CG is lower and there is an extra degree of bounce so you can still the ball in the air easily.

The 3% thinner face ensures a faster ball speed on impact and the Hydropearl 2.0 finish ensures you can game these irons effectively in any weather.

The G430’s are a serious contender overall in the game improvement market in 2023.

Mizuno JPX 923 Hot Metal Irons First Impressions

Straight out of the gate the JpX 923 look great, they are not big and chunky like some game improvement irons, but they are not the most forgiving irons on the market either. One thing is for sure, the 923 Hot Metal irons are built for distance.

The irons come in 3 flavors:

JPX 923 Hot Metal High Launch – for slower swing speeds to get the ball in the air.

JPX 923 Hot Metal – Perfect for Mid Handicappers looking for distance, forgiveness and stability.

JPX 923 Hot Metal Pro – Aimed at consistent iron strikers with more precision, control and workability. Likely to compete with the forged version and the

The next thing that stands out is the V-Chassis on the back which completes the excellent looks of the irons.

It also adds stability to the club face, improves the feel and dampens vibrations on any mishits.

These clubs are faster thanks to the new Nikol Chromoly material that the cup face, and cavity back designed clubs are made with.

It is 35% stronger which a stronger impact and more distance. It also allows the club face to be 8% thinner meaning a better energy transfer. The thinnest point of the face is now also 18% larger and the bigger sweet spot results in better shots on the off-center strikes.

More bounce and stronger lofts also add to the effect of more distance and a higher loft. The extra bounce helps to generate a higher ball flight.

While not being the most forgiving of game improvement irons, they look excellent at the address and offer a ton of distance for players with moderate to average swing speeds and beyond.

The Hot Metal irons are not going to be the best option for beginners and inconsistent strikers but they will be excellent for anybody looking for maximum distance and excellent control, especially in the shorter irons.
