Lofts and lies are the factory standard build. Individual clubs may differ if they have been bent, re-shafted or re-gripped during their life.
Length note: These lengths use the USGA / R&A measuring method, which Mizuno adopted for its published spec tables with this generation. They read about a quarter inch longer than the figures Mizuno published for earlier models such as the JPX923 and Mizuno Pro 241, 243 and 245, but Mizuno states that actual club length is unchanged. Subtract 0.25 inches to compare with an older Mizuno chart.

About the Mizuno Pro M-15
The Mizuno Pro M-15 is the players-distance model of Mizuno's 2026 Pro "Modern Series", the successor to the Pro 245 and the more forgiving companion to the M-13. The 4 through 8 irons are hollow-body: a Grain Flow Forged 4135+ Chromoly face and neck welded to a stainless steel back, with suspended tungsten inside the head — 51 g in the long irons and 50.3 g in the mid irons — while the 9-iron through gap wedge use a partial-hollow Grain Flow Forged 1025E HD body. The Contoured Ellipse CORTECH face runs through the 8-iron. Lofts are about a degree stronger than the Pro 245 in the middle of the set — 29 degrees at the 7-iron against the 245's 30 — with the same 43-degree pitching wedge and 48-degree gap wedge, and the set is right-hand only in 4-GW. Mizuno unveiled the Modern Series on 5 January 2026, with presale from 19 January and in-store availability on 5 February 2026.

Frequently asked questions
What is the loft of a Mizuno Pro M-15 7-iron?
The Mizuno Pro M-15 7-iron has a loft of 29 degrees, with a 62-degree lie and a 37.25-inch steel-shaft length.
What is the difference between the Mizuno Pro M-15 and M-13?
The M-15 is the players-distance model, with hollow-body 4-8 irons, tungsten weighting and lofts around three degrees stronger (29-degree 7-iron against the M-13's 32). The M-13 is the players cavity-back with traditional lofts and a three-way split forged construction.

No. Mizuno's specification page lists the M-15 as right hand only in 4-iron through gap wedge, while the sibling M-13 is offered in both right and left hand.
Where it sits in the lineup
Introduced in 2026, the Mizuno Pro M-15 is a current players distance set in the Mizuno range as of September 2026, with no replacement announced. It replaced the Pro 245. New sets are built to the standard lofts, lies and lengths in the chart above, though a fitting can move any of them — so confirm the numbers on the order sheet. Used sets appear on eBay, and should be measured against this chart before buying.
- Length basis: Mizuno's own specification page for the Mizuno Pro 243 (mizunogolf.com, retrieved 29 September 2026) states that Mizuno is changing its official iron measurement method to match the USGA / R&A standard and that its published lengths are consequently about 1/4 inch longer while actual club length is unchanged.
