Mizuno · Irons · 2026
Pro M-15
CaddyIndex™ breakdown — what the agentic research found across each of the six performance dimensions, with cited sources.
Single-digit to mid handicaps (3-16) at 80-110 mph swing speeds who want the longest hollow-body players-distance iron of 2026 with Mizuno feel.
High handicaps who need true game-improvement forgiveness, or buyers who prioritise stopping power and shot shaping over raw distance.
Pros
- Best hollow-body iron the brand has produced per editorial coverage.
- 10 yards more carry with a 7-iron vs M-13 sibling; significantly longer than M-13 across the bag.
- Hot face adds 5-8 yards + 51g tungsten suspended in 4-7 irons (up from predecessor's 47g) for higher launch and forgiveness.
- Feel is where the M-15 truly shines — soft, responsive feel despite the hollow and multi-piece construction.
Cons
- Premium pricing at $215/club ($1505 for 7-piece set) — same as M-13 but a hollow-body construction.
- Industry tester: too close to a blade — punishes off-centre strikes.
- 29° 7-iron loft (5° stronger than predecessor) trades stopping spin for distance — not for buyers who prioritise green-holding.
By dimension
Forgiveness
Editorial coverage: Forgiveness is excellent for an iron that looks like this. Off-centre hits leaked slightly right or left but never felt wildly offline, and distance loss was minimal. 51g tungsten suspended in 4-7 irons (up from predecessor's 47g). Industry tester: near impossible to miss. Slight improvement over predecessor via bigger tungsten payload — though tester notes toe and heel shots suffered distance-wise.
Distance
Editorial coverage: M-15 is significantly longer than the M-13 across the bag with M15s produced 10 yards more carry with a seven-iron. Industry awards: hot face that adds five to eight yards. 7-iron loft 29° — substantially stronger than predecessor's 34° (5° stronger). 51g tungsten + hollow body + thinner Grain Flow Forged 4135 Chromoly face delivers major distance step-up. The brand's longest hollow-body iron yet.
Workability
Industry awards: consistent distance with a slight draw from a heavier, smallish head. Compact players-distance silhouette + tungsten low/back CG produces neutral-to-draw trajectory bias. 29° 7-iron loft (5° stronger than predecessor) compresses spin loft and trims shape-shifting ceiling. Slight workability regression vs predecessor — trade-off for the distance gains.
Feel
Editorial coverage: The feel is where the M-15 truly shines. Despite the hollow and multi-piece construction, it delivers the soft, responsive feel that players crave, and crucially, this feel is incredibly consistent across the entire set. Industry awards: remarkably soft, satisfying strike. Industry tester: excellent feel off the face. Major step up vs predecessor's hollow-body feel via the family-wide 2026 tuning.
Sound
Editorial coverage notes the family-wide 2026 acoustic refinement carries over from the M-13 platform. Hollow body + tungsten + Grain Flow Forged Chromoly construction produces refined acoustic vs predecessor baseline. Same caliber as M-13 sibling acoustic standard.
Looks at address
Industry awards: players-iron look, superb turf interaction that plows through turf, and consistent distance with a slight draw from a heavier, smallish head. Industry tester: super thin yet plays like a game-improvement iron. Premium players-distance silhouette refined from predecessor — marginal aesthetic uplift.
