PLAYER TESTING TAKEAWAYS
“Sleek and pretty profile. Doesn’t feel clicky. Great power behind. Broad sweet spot. Distance was predictable but not explosive.” – Jeff Smith (12-handicap) on the Mizuno Pro S-3 irons
“Clean thin topline. Soft and forgiving feel. Small profile. I’m buying!” – Mike Parziale on the Mizuno Pro S-3 irons
Mizuno Pro 24x Irons
WHAT YOU NEED TO KNOW
The new Mizuno Pro Signature series irons are designed to cater to the most elite ballstrikers and live on for about a four-year life cycle. The Mizuno Pro 24X line isn’t going away either, and the new Mizuno Pro S-3 will slot into the lineup somewhere between the current 241 blades and the 243 cavity-back irons.
The Mizuno Pro S-3 uses Mizuno’s Grain Flow Forging process from 1025E Pure Select Mild Carbon Steel and features a copper underlay that has been present since the Mizuno MP-20 to further soften the feel.
The Pro S-3 irons also incorporate Mizuno’s Triple Cut Sole to enhance turf interaction by slightly beveling the leading edge and hard-cutting the trailing edge to make for a quick and clean exit.
Mizuno Pro, a.k.a. Mizuno MP, irons have always been distinctive, and now for 2024 Mizuno is once again refining what it means to truly be a Mizuno Pro iron with the release of the 24X series, which includes the 241 blades, the 243 speed cavity and the 245 hollow body built for precision distance and Tour-level speed.
The biggest focus for the Mizuno design team with the new 24X line was to dig into what each iron truly means to the golfers it’s intended for, and after taking positive and constructive criticism about each model, the engineers went to work with no stone left unturned to make sure each model was a better fit.
The Mizuno design team stressed every possible detail they could to make sure each model lived up to the lofty expectations bestowed upon them, and with that in mind, they believe they have delivered on those, while also making each iron slightly smaller than the previous generation.
The Mizuno Pro 241 blade is just that, a pure-as-can-be muscle back intended to deliver the utmost in feel, control and looks for the discerning golfer.
The evolution from the previous blade includes better turf interaction thanks to a new sole geometry and a tapered blade design to help the iron actually appear smaller from the address position without sacrificing feel. Last but not least, to help deliver greater control, the 241s have a shorter blade length than the previous 221 through the entire set.
If you thought the blade was an evolution, wait until you find out what they did to the 243. Improvements include wider and longer micro-slots to boost ball speeds and increase launch, a fresh sole shape for better turf interaction, a much more compact look from the address position and a better blending of lofts into the shorter irons.
The loft strengthening was a direct result of golfers using the previous 223 irons to blend into the 225s, and these new specs prevent the need for after-the-fact bending to ensure no large distance gaps.
Much like the previously discussed 241 and 243, the Mizuno Pro 245 has gone the opposite of many irons in its category of hollow players distance and focused on the “players” by slightly shrinking in size and address profile. Add that to the adjusted sole shape and you have a club intended for distance hidden in a much smaller player’s preferred package.
