Mizuno Pro 223 Vs Mizuno 243 Irons Comparison Overview


Do the newer Mizuno Pro 243 irons represent a significant improvement over the 223s? Let’s find out.

Mizuno Pro 223 Irons Overview


“The 223 irons are forged with chromoly, the long irons are 1025E mild carbon and have a cavity back design.”

The offset is moderate and the Mizuno Pro 223’s are compact so they frame the ball really nicely.

The lofts are relatively weak so in conjunction with the compact heads, I was able to impart enough spin on the ball to shape my shots at will.

The Mizuno Pro 223’s are very workable even as they are a bit larger than other Mizuno models. They sell for about $1,100.

Mizuno 243 Irons Overview

The Pro 243’s feature increased bounce angles, flow microslot in the mid/long irons and are grain flow forged.

The profile is very similar to the 223s but the cavity has been refined a bit and the angles are softer.

The Pro 243 irons also feature a wider flow microslot than the 223s which made for better low-face forgiveness. They also feel smoother through the turf. The Mizuno Pro 243 irons retail for $1400.


Given that the Pro 223’s and 243’s are meant to be the more forgiving Mizuno models, the Mizuno Pro 243’s do in fact surpass the 223’s. They are more forgiving and play better from the rough.

Mizuno Pro 223 Irons – First Impressions

A first introduction for the legendary Mizuno Pro series to the Western Markets. These are compact players cavity irons that have the profile that tour players demand coupled with the distance they didn’t know they needed.

While the pro series had been reserved for Japanese markets until now, the surging popularity that Mizuno have enjoyed in recent years has lead to their most prestigious family of irons making it to the west and they don’t disappoint.

Forged in Hiroshima, Japan, the 223’s are built with tour players in mind with their compact heads and despite the players profile, there is a ton of technology driving these irons to deliver distance, control, consistency and workability as well.

The 4 – 7 irons are built is a different way as the importance of COR diminishes and the importance of loft increases in the scoring irons.

The 4 – 7 irons have a Forged Chromoly face that is only 2.4mm (The JPX921 Forged is 2.6mm) thick and works with the Microslot inside the bevelled back edge to offer fast ball speeds, flex and a better rebound.

The 8 – GW have a 1 piece, 1025 mild carbon steel, grain flow forged construction and sport wider soles and longer blade as loft becomes more of a determining factor and these precise irons offer high launch, distance a steep descent angle for stopping power on the greens.

There is a microlayer of copper underneath the Nickel Chrome coating which lends to tour level feel and the irons have been accoustically primed to sound perfect on impact.

These irons are reserved for the better players only and with the compact shape it is very unlikely that mid handicappers will feel comfortable with these irons.

“The Mizuno Pro 243 irons follow the tradition of the Mizuno Pro 223 irons in the sense that they are both tour cavity irons that meet the demands of better players.”

The Mizuno Pro 243 irons feel immediately satisfying whether you’re teeing off on an executive course with one of the long irons or chipping in with a short iron.

They are single-piece grain flow forged in Mizuno’s legendary Hiroshima facility and feature premium appointments.

For instance, all of the irons in the set feature a copper underlay to enhance the soft feel of the mild carbon steel and chromoly materials. This allows for immediate response at impact.

You will know exactly where you made contact with the ball based on feel alone.

To further fine-tune the precise feel of these irons, Mizuno used what they call Harmonic Impact Technology.

This feature was included to mimic the feel and response of a true muscle back blade.

The Mizuno Pro 243 irons also feature a wraparound sole grind. This makes the soles appear visually smaller while providing significant relief through the turf.

Adding to the smooth turf interaction is an increase in bounce angles. There is a 1 degree increase in long irons and a 2 degree increase in the short irons.

Visually, the Mizuno Pro 243 irons look stunning. They have undergone a full satin brush which helps reduce glare and imparts a monochromatic aesthetic.

The top lines are on the thin side and the soles are well-hidden. All of this adds up to a cavity back iron that looks incredibly sleek and workable.

“The Mizuno Pro 243 irons are certainly for players who want a premium feel and the ability to work the ball from any lie.”

The 223’s are the upgrade to the MP-20 MMC irons but they are smaller and more compact with a faster face thanks to the Chromoly face and microslot.

The Irons can be considered a smaller version of the very popular JPX921 Forged irons which have thicker faces and are more forgiving.

The Mizuno Pro Family of Irons

“Included in the latest iteration of Mizuno’s Pro series are the Pro 245 and Pro 241 models.”

The Mizuno Pro 241 irons are the true blades in the family. They are single-piece forged from 1025 carbon steel and feature a muscle back design.

They also feature progressively tapered blades – wider in the long irons and narrower in the short irons.

The Mizuno Pro 245 irons feature a hollow body design and are also grain flow forged from 1025E carbon steel.

These are most likely the most forgiving irons in the new Mizuno Pro series as they tend to play the longest of the three sets.

The Pro 245’s also feature a cap of 17-4 stainless steel behind the hitting zone to push ball speeds.
