About the Mizuno JPX-921 Tour

The JPX 921 Tour is the compact players model of the JPX 921 family, Grain Flow Forged HD from 1025E Pure Select mild carbon steel in Hiroshima. It keeps the Stability Frame with toe-bias weighting introduced in the JPX Tour line, adds a thicker cavity pad behind impact for feel, narrows the soles of the short irons and wears an anti-glare pearl brush finish. Lofts are traditional — 34 degrees at the 7-iron, 46 at the pitching wedge — with a tight offset progression from 0.126 inches at the 4-iron to 0.098 at the gap wedge. The stock set is 4-GW: Mizuno's 2019 tour audit found not a single JPX 919 3-iron in play, so the 3-iron was dropped, and left-handers were served 6-GW through the JPX 921 SEL programme. Mizuno announced the JPX 921 line on 10 August 2020 with retail from 17 September 2020, and the successor JPX 923 family was unveiled in September 2022.

Frequently asked questions

What is the loft of a Mizuno JPX 921 Tour 7-iron?

The Mizuno JPX 921 Tour 7-iron has a loft of 34 degrees, with a 61.5-degree lie and a 37-inch steel-shaft length.

Why does the Mizuno JPX 921 Tour set start at the 4-iron?

Mizuno's 2019 tour audit found not a single JPX 919 Tour 3-iron in play, so the JPX 921 Tour was offered 4-iron through gap wedge, with the MP-20 HMB suggested to fill the 3-iron slot.

Are the Mizuno JPX 921 Tour irons forged?

Yes. They are Grain Flow Forged HD from 1025E Pure Select mild carbon steel at Mizuno's Hiroshima facility.

Finding a used set

The Mizuno JPX-921 Tour ran from 2020 to 2022 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:
  • Mizuno official Australian JPX921 Tour product page, mizunogolf.com/au/golf-clubs/jpx921-series/jpx921-tour/ (Specification tab: club, loft, lie angle, offset in inches, length; dexterity 'RH: 4-GW, LH: 6-GW as part of JPX921 SEL'), archived 27 January 2022 via archive.org. The table carries no bounce or swing weight columns, so those keys are omitted
  • Same archived page, product copy: Grain Flow Forged HD from 1025E Pure Select mild carbon steel in Hiroshima, Stability Frame with toe-bias weighting, thicker cavity pad (Harmonic Impact), narrower workshop-refined short-iron soles, pearl brush finish, and the note that Mizuno's 2019 tour audit showed no JPX919 3-irons in play, hence the 4-GW set
  • 2nd Swing Golf and TGW spec tables for the JPX 921 Tour — corroborate the loft, lie, length and offset figures above (TGW lists the gap wedge at 35.5 inches where the official table says 35.25; the official figure is used)
  • Plugged In Golf JPX921 Tour review (October 2020) and Golf Business News / Golf Monthly launch coverage — the JPX921 line was announced 10 August 2020 with retail from 17 September 2020. year_discontinued is 2022, the year Mizuno unveiled the JPX923 family (September 2022), although the JPX923 Tour itself only reached retail in February 2023
  • No single stock shaft is listed because Mizuno sold the JPX921 Tour through its custom programme with a broad no-upcharge shaft matrix (Nippon Modus, KBS Tour, Dynamic Gold, Project X and others per the archived Australian page), so the stock_shafts key is omitted
