Performance index
Six researched ratings, lower (blue) through to elite (gold).
Where it wins
- Feel92
- Sound90
- Looks88
Watch
Rated highest for feel and sound; its softest dimension is forgiveness.
Single-digit to mid handicaps (3-15) at 85-110 mph swing speeds who want Mizuno feel in a distance-iron package with extra long-iron forgiveness over a Tour cavity.
Higher handicaps who need maximum off-centre forgiveness, or pure shape-shifters who want a more workable, accuracy-first iron.
Pros
- Top-10 finish in the 2023 Players Distance robot test: 6th for forgiveness, 6th for distance.
- Launch monitor testing: 167-169yd 7-iron carries — 2-yard spread shows exceptional dispersion.
- V-Chassis with Harmonic Impact Technology delivers signature feel/sound in a Forged distance package.
- Half-club longer than predecessor per editorial coverage — face thinned 2.6mm → 2.2mm.
Cons
- Independent robot testing: accuracy ranked 11th overall — the iron's weakest attribute and the reason for its 10th-overall placement.
- Reviewer testing flagged the 'Pro to Mid Handicap' positioning as overly ambitious — closer to a single-digit iron in practice.
- Modest evolution: not a significant upgrade over the predecessor, but an upgrade nonetheless.
By dimension
Forgiveness
ModestIndependent robot testing: 6th overall for forgiveness in the 2023 Players Distance category, with consistent ball-speed retention and dispersion control. New micro-slot milled behind the 4-7 iron faces allows the face to flex more across a wider area. Stability Frame retained with refined toe-bias weighting. Reviewer testing: forgiveness sits between the HMP and Tour — a meaningful step up from the more demanding predecessor. Editorial coverage: forgiveness is exceptional, nowhere more apparent than the long irons.
Distance
ExcellentIndependent robot testing: 6th overall for distance in the 2023 Players Distance category. Editorial coverage: predecessors were plenty long, but the 923s are longer by half a club or more. Face thickness reduced from 2.6mm to 2.2mm enabled by 3rd-generation Chromoly Forging. 7-iron loft strengthened from 31° to 30°. Launch monitor: elite ball speed throughout the set with 167-169yd carries showing tight dispersion.
Workability
StrongIndependent robot testing: accuracy ranked 11th overall — the iron's weakest attribute. The micro-slot face design trades some predictability for face flex, capping shot-shaping ceiling slightly vs the more controlled predecessor. Reviewer testing: launch angles strong, spin closer to the Tour — high enough spin to flight shots both ways for a skilled player. Shorter blade lengths and more compact head reward intentional shot shaping for the better player.
Feel
Class-leadingEditorial coverage: V-Chassis design, developed through Harmonic Impact Technology, creates a denser and more satisfying feel at impact. Reviewer testing: medium-soft and conventional with just a hint of pop; sound/feel rated exceptional. Same 1025E Pure Select carbon steel in 8-GW + 4120 Chromoly in 4-7 iron construction. Substantial upgrade over the JPX 921 Forged in feel. Harmonic Impact Technology arrival in the Forged line tunes vibration patterns for hallmark Mizuno solidity.
Sound
Class-leadingEditorial coverage: Acoustic Sound Ribs precisely dial in specific vibration patterns for a solid, explosive impact sound. Reviewer testing: low-pitched tock that's traditional but with a hint of explosiveness. Reviewers consistently note the acoustic is noticeably quieter and more solid vs the predecessor. The V-Chassis cavity design with Harmonic Impact Technology delivers the brand's signature acoustic in a Forged distance package.
Looks at address
ExcellentEditorial coverage: blade lengths are shorter than the predecessor, with the biggest differences found in the scoring irons; sleeker, more compact, more forgiving and longer than predecessors. Reviewer testing: safely in the players category, toward the thicker side. Grain Flow Forged satin chrome finish with refined topline and reduced offset. The biggest visual evolution vs predecessor is the compactness of the scoring irons.
