MIZUNO IRON REVIEWS
Mizuno JPX 921 Hot Metal
We tested: 4-PW, GW, SW, LW
Our take: If you want to hit the ball long, high and straight but still want an iron that feels buttery smooth, this may very well be the iron made just for you. Our club testers feel strongly about these claiming “mishits aren’t punishing at all,” and “shot dispersion was incredibly tight.” Furthermore, considering these are so forgiving, they don’t look like it. Mizuno masterfully tucked a monster truck worth of technology in a beautifully compact design.
Mizuno JPX 921 Hot Metal irons
Mizuno JPX 921 Forged irons
The details: Grain Flow Forged Chromoly 4120 enables the face to be ultra-thin for a faster ballspeed and a CNC-milled slot behind the face pushes weight farther toward the perimeter for more forgiveness. A Stability Frame with toe bias offers less twisting of the face at impact. The compact shape comes in an anti-glare Pearl Brush finish for fewer distractions over the ball.
Mizuno JPX 921 Tour
We tested: 4-PW, GW
Our take: Known as the go-to iron among touring professionals not on the Mizuno tour staff, the 921 Tour irons are a beautiful marriage of traditional shaping and new technologies. The reason being is simple — the modern player wants consistency first as they tend to hit high, straight shots more often than they do big draws and fades. Mizuno knows this, and these irons are stable and forgiving, but also can be used for shotmaking when needed. Oh, and they feel like hot butter in the hands.
Mizuno JPX 921 Tour irons
The details: Grain Flow Forged with a Stability Frame with toe bias weighting for more stability at impact for straighter shots and a more consistent/predictable ballflight. Also comes with Mizuno’s Harmonic Impact technology with a thicker cavity pad, helping to avoid vibration and lend a truly unique feel.
Mizuno Pro 221
We tested: 3-PW
Our take: If there’s a player’s iron that evokes pure nostalgia while still being refined enough for the modern game, it’s hands down the new Pro 221 irons from Mizuno. These irons exude what it means to be a gamer’s blade, but with some subtle touches to make what’s otherwise a traditional blade more playable. You can shape shots with ease using these and can expect them to not only feel like a forged Mizuno blade but actually better than any Mizuno forged iron you’ve ever tried, thanks to some innovative copper inlays beneath all that gorgeous chrome.
Mizuno Pro 221 irons
The details: Grain Flow Forged from pure 1025E mild carbon steel, these irons also come with a microlayer of copper underneath the chrome for a remarkable soft feel. Mass has been repositioned from the heel toward a muscle-back behind the center for a slightly muted sound, and the shorter/more compact feel is designed to enable greater shotmaking versatility. The 8-PW are also noticeably smaller for a controlled ballflight.
Mizuno Pro 223
We tested: 4-PW, GW
Our take: An elite player’s cavity-back iron from Mizuno, the Pro 223 mixes a dash of forgiveness with plenty of shotmaking control for what we think is one of the best irons ever made by Mizuno (and that’s saying a lot). Speaking of the Pro 223 our testers said, “it hides some technology inside there that feels unbelievable,” and “this iron has serious player vibes, but the added bit of forgiveness makes me feel like I can get away missing the sweetspot from time to time.” Lastly, “the trajectory with these is amazing” and “the workability is superb. I can hit it straight or with a fade or draw — all on command.” Need we say more?
Mizuno Pro 223 irons
The details: Made via a Grain Flow Forged construction with a soft copper underlay for added feel, the Pro 223 has a Flow Microslot behind the face resulting in a thin clubface for faster ballspeeds and a beveled back edge for more versatility. The headshape is compact — especially in the shorter scoring irons — a feature commonly requested by tour players.
Mizuno Pro 225
We tested: 2-PW, GW
Our take: It’s easy to be fooled by how the 225s look. At a glance they look like straight blades, but what you can’t see is these are actually the most forgiving and playable of the new Pro irons this year. Inside the long and middle irons is a hollow-cavity design that packs more ballspeed and forgiveness. According to some testers, “it’s like hitting a blade with more forgiveness and more juice,” and “the ball goes and goes” and “I can easily put these in my bag right now.”
Mizuno Pro 225 irons
The details: The Pro 225 irons feature a Grain Flow Forged hollow-body construction for added forgiveness, and like the other new Pro irons has a copper underlay for better feel. Additional tech includes a 4135 Chromoly face and neck and an internal tungsten weight (2-7) for higher and more stable ballflights. The 9-PW models are pure select mild carbon steel for a penetrating trajectory and more shotmaking maneuverability.
