Taylormade P790 Vs Mizuno JPX923 Hot Metal Irons Comparison Overview

Taylormade P790 Vs Mizuno JPX923 Hot Metal Irons

When a lot of players think of Mizuno, they think of beautifully forged golf clubs.

Mizuno is known for their grain flow forging that imparts an astonishingly soft feel to their clubs. But those aren’t the kind of clubs we will be talking about today.

The Mizuno JPX923 Hot Metal irons are not in fact forged but rather cast. Surprisingly the Taylormade irons we will be comparing the Mizuno JPX923 Hot Metal irons to today are forged.

But in this case, how much does forging vs casting play a role? Which irons are better overall? Let’s talk about it.

Taylormade P790 Irons Overview

“The P790 irons have a forged hollow body design which gives them a unique feel and great overall distance.”

With the hollow body design, you get increased flex and great ball speeds. In fact, our testers were noticing 2-3 MPH increases in ball speeds.

The P790 irons also have l-shaped face inserts that increase forgiveness on low-face shots.

However, our testers also noted that the flight in the long irons was a bit erratic.

It seems the unsupported face is a bit unstable and fading the ball was almost unavoidable unless you were spot-on with your strike.

The Taylormade P790 irons are also a bit chunkier behind the ball when compared to the Mizuno JPX923 Hot Metal’s.

The forging did impart a soft feel; but the hollow body design almost works against these irons in terms of accuracy.

Mizuno JPX923 Hot Metal Irons Overview

“These cast irons are made from nickel chromoly which allows for very thin milling without losing much strength.”

By contrast, the Mizuno JPX923 Hot Metal irons not only felt stable; they were stable.

Flight was much straighter even on mis-hits and repeatable distances were very consistent throughout the set.

This can be attributed to the one piece cavity construction.

While the Mizuno JPX923 Hot Metal irons have a more compact shape and shorter blade, the top line is still moderately chunky so it doesn’t look terrible for high handicappers at address.

The short irons in this set also spin at a high rate which is exactly what you want around the pin.

“Despite being cast irons, the overall performance of the Mizuno JPX923 Hot Metal’s was better.

They were more stable, more accurate and at least as long and forgiving as the Taylormade P790s.”

Taylormade P790 – First Impressions

The first thing to notice about the P790 irons is the compact, forged heads that come in a shape and style that will suit the better players.

Despite the players feel of the irons, they also come packed with technology that will add distance and forgiveness like the Thru Slot speed pocket, speed foam and inverted cone technology which allows more flex on impact.

The forged irons are actually a hollow construction, filled with speed foam which allows much greater distances to be achieved than the original P790’s and the tungsten weighting keeps the CG low for an easy launch for an iron of this type.

The original P790 irons, released in 2017, were definitely for the players but with the remodelling in 2019, these can also be used for mid handicappers looking to test the waters of players irons.

All in all, definitely not for the high handicappers.

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.
