Ping G425 Vs Mizuno JPX921 Hot Metal Irons Review & Specs 2023

There are a some irons that straddle the line between tour grade and the game improvement category. Some would say that the two iron sets that are the subject of today’s review are two such sets that blur the lines.

And with good reason. Brooks Koepka has used one of these sets to great success despite the fact that they are marketed more towards amateurs.

In any case, we wanted to take a closer look at these two iron sets to see how they stack up against each other. Read on to see what we found.

Overview Of Both Iron Sets

The Mizuno JPX921 Hot Metal irons are the 3^rd of their generation.

They are also the third iteration of Hot Metal irons to utilize Chromoly steel which, is an alloy steel that combines chromium and molybdenum.

Chromoly is said to be a highly resilient steel that allows for superior flexing.

The Ping G425 irons are the latest in a long line of G irons that have become known for their forgiveness.

With the G425, Ping has shrunk the blade size a bit from the last entry in the G series to give these clubs more of a player profile.

Ping G425 Key Features

The Ping G425 irons features a metal-wood style face made out of 17-4 stainless steel.

The thin steel coupled with the top undercut allows the face to function like a hinge – producing a high degree of flex and ball speed.

Ping has also pushed the boundaries of perimeter weighting with tungsten in the hosel and toe.

Mizuno JPX921 Hot Metal Irons Key Features

The star of the show here is the Chromoly alloy that flexes and recovers with lightning speed.

These irons also feature a cup face architecture which, expands the borders of the sweet spot.

There are also sound ribs in the head of these irons that produce a low, satisfying sound on impact.

G425’s Vs G410’s

The G425 irons are the successor to the G410’s. The first thing you will notice is that the G425 blade length is slightly shorter than the 410’s.

This gives them a more premium, player’s profile. The badge design has been streamlined as well but as far as distance goes, there is little difference between the 2 models.

Mizuno JPX921 Hot Metal Vs. 921 Hot Metal

The Mizuno JPX921 Hot Metal irons have come a long way from the 919 model. For one thing, they play longer.

They feature stronger lofts for more precise approaches and better control in face of hazards.

The steel feels more refined as well; affording softer, gentler feedback.
