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 are the figures Mizuno published at launch, measured by its traditional method. Mizuno has since moved its spec tables to the USGA / R&A method, which lists the same clubs about a quarter inch longer (37.25 inches at the 7-iron rather than 37.0); Mizuno states that actual club length is unchanged. Newer Mizuno charts, from the JPX925 onward, use the longer figures.

About the Mizuno Pro 241

The Mizuno Pro 241 is the muscle-back of the 2024 Mizuno Pro series and the direct replacement for the Pro 221. It is one-piece Grain Flow Forged HD from 1025E Pure Select mild carbon steel in Hiroshima, with mass gathered centrally behind impact, a soft copper underlay and a full satin brush finish. Lofts carry over unchanged from the Pro 221 at 34 degrees in the 7-iron and 46 degrees in the pitching wedge, but bounce was raised by one degree in the long irons and two degrees in the scoring irons, and the 3-iron lie is half a degree more upright. The stock set is 3-PW in right hand and 4-PW in left. Lofts, lies and lengths listed are the men's standard steel-shaft build.

Frequently asked questions

What is the loft of a Mizuno Pro 241 7-iron?

The Mizuno Pro 241 7-iron has a loft of 34 degrees, with a 61.5-degree lie and a 37-inch steel-shaft length.

What changed from the Mizuno Pro 221 to the Pro 241?

Lofts, lengths and offset are unchanged. Bounce went up by one degree in the long irons and two degrees in the scoring irons, the 3-iron lie moved from 59 to 59.5 degrees, and the head was retooled with more central mass and a thinner topline.

What is the pitching wedge loft on the Mizuno Pro 241?

The Mizuno Pro 241 pitching wedge is 46 degrees. The set runs 3-PW, so gapping below the pitching wedge is covered by separate wedges.

Finding a used set

The Mizuno Pro 241 ran from 2023 to 2025 and is no longer in production, so the used market is the only source. Search the used listings on eBay, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.

Data compiled from:

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.
