About the Mizuno MP-25

The MP-25 is Mizuno's first attempt at a forged distance iron that keeps MP lofts. It is Grain Flow Forged from 1025 Boron — the harder alloy that lets Mizuno thin the face — with a micro-slot cut behind the face to let it flex. Lofts stay traditional at 34 degrees for the 7-iron and 46 for the pitching wedge, so the gain is ball speed rather than a strengthened chart. Bounce is progressive, 2 degrees in the long irons to 6 at the pitching wedge. Figures are the men's standard steel build.

Frequently asked questions

What is the loft of a Mizuno MP-25 7-iron?

The Mizuno MP-25 7-iron has a loft of 34 degrees, a lie of 61.5 degrees and a steel-shaft length of 36.75 inches.

When were Mizuno MP-25 irons made?

The MP-25 was announced in 2015 and sold until the MP-18 family replaced the MP line in 2017.

Are Mizuno MP-25 lofts strong?

No — they are traditional MP lofts, 34 degrees at the 7-iron and 46 at the pitching wedge. The MP-25's extra distance comes from a thinner Boron face and a micro-slot, not from a strengthened chart.

What is 1025 Boron?

A carbon steel with boron added, about 30 per cent stronger than the plain 1025 Mizuno uses elsewhere. The extra strength lets the face be forged thinner without denting.

Finding a used set

The Mizuno MP-25 ran from 2015 to 2017 and is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.

Data compiled from:
  • 2ndswing.com Mizuno MP-25 Iron Set specification table — loft, lie, offset, bounce and length for the 3-iron through pitching wedge, the 3-PW / 4-PW-SW / 7-PW set ranges, the Project X 5.5 and 6.0 stock shafts, and the Grain Flow Forged 1025 Boron construction with the micro-slot behind the face.
  • Note on the years: Mizuno announced the MP-25 in 2015 and it was sold into the 2016 season; year_introduced records the announcement year per this database's convention. year_discontinued marks the arrival of the MP-18 family in 2017, which replaced the whole MP range.
  • Note: swing weight was not published in the source consulted and is omitted rather than estimated.
