Best for

Single-digit to mid handicaps (5-15) at faster swing speeds (85-105 mph) who prioritise raw distance and Mizuno feel in a players-distance silhouette — and who can deliver the strike.

Avoid if

Anyone who mishits frequently or wants forgiving long irons — the compact chassis penalises off-centre contact and competes with the standard 923 Hot Metal in that lane.

Pros

  • Top-3 in 2023 Players Distance test for distance — 126.7 mph ball speed, 195.8yd carry on 28.5° 7-iron.
  • 2nd in raw ball speed in the entire 15-model PD test.
  • Middle-of-face strikes 'absolutely wonderful' per reviewer testing — V-Chassis delivers hallmark feel/sound.
  • Compact head + 0.126" offset + thinner topline — premium players-distance silhouette aimed at confident strikers.

Cons

  • 13th overall for forgiveness — does not produce consistent outcomes off the club face.
  • Forgiveness regression vs the predecessor — the smaller, thinner-faced chassis amplifies off-centre penalties.
  • Strong 28.5° loft + low 13.7° launch + 3348 rpm spin = limited stopping power on firm greens vs softer-lofted PD peers.

Forgiveness

Independent robot testing: 13th overall for forgiveness — does not produce consistent outcomes off the club face. Compact head + minimal offset + thinner topline reduce perimeter mass vs the standard 923 Hot Metal sibling. Stability Frame retained with toe-bias weighting but the smaller chassis limits the effective hitting zone. Notable regression vs the predecessor — the loft jacking and thinner face amplify off-centre penalties.

90

Distance

Independent robot testing: 3rd overall for distance — 126.7 mph ball speed, 195.8 yd carry, 205.3 yd total on the 28.5° 7-iron. Ball speed ranking: 2nd in the entire 15-model test (only one model faster). 4335 Nickel Chromoly (35% stronger than predecessor) enabled 8% thinner face. 7-iron loft 28.5° (0.5° stronger than predecessor's 29°). Reviewer testing: middle of the face are absolutely wonderful to hit. One of the longest players-distance irons of 2023.

76

Workability

Compact head with shorter blade length, minimal offset (0.126" on 7-iron) and thinner top edge — geometry tuned for shot shaping. Editorial coverage: compact design and minimal offset make it easier for confident ball-strikers to shape their shots and control the trajectory of the ball. Launch angle 13.7° + 3348 rpm spin — a flat, low-spin trajectory profile that flights both ways for skilled players. Still bounded by strong lofts and Stability Frame's toe-bias.

84

Feel

Reviewer testing: when hit in the middle of the face, these irons are absolutely wonderful to hit. V-Chassis construction with Harmonic Impact Technology delivers hallmark vibration tuning — a step up from the predecessor architecture. The 4335 Nickel Chromoly face flex contributes a measurable hint of pop on solid strikes. Smaller head concentrates feedback for sharper feel discrimination on off-centre strikes vs the standard 923 Hot Metal.

84

Sound

V-Chassis architecture with Acoustic Sound Ribs precisely dial in vibration patterns for a solid, controlled impact sound. Editorial coverage notes the family's acoustic is noticeably quieter and more solid vs the predecessor. Smaller, more compact head delivers a tighter, more refined acoustic vs the standard 923 Hot Metal. Shares the family's premium acoustic character in a players-distance silhouette.

85

Looks at address

Editorial coverage: heads are compact and sit nicely behind the ball but under the hood these irons have the technology to produce crazy ball speeds. The matte chrome finish is subtle but there's just enough shine for these to really catch your eye. Manufacturer: shorter blade length, thinner topline, and minimal offset inspire confidence at address and provide the workability better players demand. Premium players-distance silhouette — a real step toward the players-iron aesthetic.
