Single irons
1 single iron is listed. Choose the one you need: Complete my set matches it to your hand and flex, with same-spec irons from other generations alongside.
Each club is one of a kind: check the clubs included, shaft and condition at the store before you buy. Condition is each store's own grade (see how grades compare). Store photos show the model, not the exact club you'll receive: the grade and the store's description tell you its condition.
Combo sets
These sets mix the Mizuno JPX 921 Hot Metal Pro irons with the Mizuno JPX 921 Forged and Mizuno JPX 921 Tour: often longer irons from one and shorter irons from the other. The store doesn't say which clubs are which, so check the photos or ask the store before you buy. Combo sets aren't counted in the prices above.

Factory specs
Standard men's steel-shaft specs. Lengths are Mizuno's own measure, as on its spec sheets; retailers that use the USGA measure list each club 0.25 in longer. A used club may have been bent, reshafted or cut down since, so compare these with the listing.
| Club | Loft | Lie | Length |
|---|---|---|---|
| 4 | 19° | 60° | 38.5 in |
| 5 | 22° | 60.5° | 38 in |
| 6 | 25° | 61° | 37.5 in |
| 7 | 29° | 61.5° | 37 in |
| 8 | 34° | 62° | 36.5 in |
| 9 | 39° | 62.5° | 36 in |
| PW | 44° | 63° | 35.5 in |
| GW | 49° | 63° | 35.25 in |

Sets with identical specs
Mizuno JPX 921 Hot Metal has the same loft, lie and length on every club it shares with this set, so a single iron from one fills a gap in the other. The head design and stock shaft can differ, so the club may look different from the rest of your set.
Other Mizuno JPX irons from 2020
This set has a 29° 7-iron. Mizuno also made the Mizuno JPX 921 Hot Metal (29° 7-iron), Mizuno JPX 921 Tour (34° 7-iron) and Mizuno JPX 921 Forged (31° 7-iron). Same family and year, but each has its own head and specs, so check the loft before mixing them.
