Ping G425 Vs Mizuno JPX923 Hot Metal Irons Comparison Overview

Ping G425 Vs Mizuno JPX923 Hot Metal

 These days, golf club manufacturers are finding new ways to shrink game improvement irons while maintaining a high degree of forgiveness.

It’s truly a great time to be a mid to high handicapper because the technology is so exciting and some of it is truly effective.

In today’s comparison overview, we wanted to test a couple of iron sets that fully display how smaller iron heads don’t necessarily mean poor forgiveness.

So let’s take a look at the Ping G425 and Mizuno JPX923 Hot Metal irons.

Ping G425 Irons Overview

“The G425’s actually have shorter blade lengths than the G410 irons.”

However, when compared to the Mizuno JPX923 Hot Metal irons, the G425 have slightly wider soles. You can see this clearly at point of address.

Blade lengths are about the same though.

The G425’s feature variable face thickness so ball speed isn’t totally lost when you hit around the perimeter of the face.

In terms of distance, the Ping G425’s were very impressive. Average distance with the 5-iron was 169.7 after three swings by our high handicap testers.

The Ping G425’s are also perimeter weighted with a tungsten toe screw and weight in the hosel. The MOI was great.

The G425’s resist twisting very well – even in the cabbage. Our only gripe was that the G425’s don’t spin very well or launch very high around the pin.

Mizuno JPX923 Hot Metal Irons Overview

“The Mizuno JPX923 Hot Metal 5-iron played generally shorter than that of the G425 set.”

After three swings each, our testers were averaging only 162.9 yards with the 5-iron of the Mizuno JPX923 Hot Metal set.

However, we really loved the short game performance of these irons.

The compact heads and slightly wider soles allow for both lateral and horizontal workability. Most of our testers didn’t mind the short blade length in the long iron either.

They have incredibly thin faces so they play hot. The thin part of the sole is also nice and wide so you get good low-face forgiveness.

“In terms of forgiveness and distance, the Ping G425’s do a better job of combining the benefits of compact blade length and game improvement. However, even the long irons of the Mizuno JPX923 Hot Metal set performed better in the rough. The Mizuno JPX923 Hot Metal irons were also superior around the pin.”

Ping G425 Irons First Impressions

After taking 2020 off, the G425 Irons are a much anticipated upgrade to the G410’s and the first thing you notice with these irons is that the heads are smaller and more compact.

The irons incorporate two weights, a visible screw at the front of the clubhead and a weight in the hosel. This, coupled with the wide and cascading sole allows a quality ball launch angle.

Ping have gone for the metal wood style material for the first time in a set of irons and the variable face thickness allows for a lot of forgiveness and ball speed on any strike, even when you hit the ball off center.

They also have a multi material badge filling in the cavity at the back to dampen any vibrations on mishits.

The irons have a slight bit of offset for forgiveness but you are going to get plenty of feel from these especially from Irons you would classify as game improvement.

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.
