How to identify this generation

• A satin cavity back with a dark recessed channel across its lower half, a Mizuno Pro script inside the channel, the runbird logo on the upper blade and 243 stamped on the hosel.
• The Mizuno Pro name also appears on these Mizuno irons; compare their markings before using this chart: Mizuno Pro S-1, Mizuno Pro S-3, Mizuno Pro S-4, Mizuno Pro M-13, Mizuno Pro M-15, Mizuno Pro 245 (2026 US page).

What to notice in the specifications

• Mizuno’s table also lists offset (0.138 in on the 4-iron down to 0.094 in on the GW) and bounce (2° on the 4-iron rising to 9° on the GW) for each club.
• The specification page lists the set as right-handed only.
• Mizuno’s page note says its published lengths follow the USGA/R&A measurement method, which reads about 1/4 in longer than its earlier method for an unchanged club; an Internet Archive capture of the product page dated 2024-02-25 shows the same figures under a “USGA/R&A Length” heading.
• The main Mizuno Pro 243 product URL now redirects to the Mizuno Pro M-13 page; the figures here come from the 243 specification sub-page that Mizuno still serves.
