About the Mizuno JPX-921 Forged
The JPX-921 Forged is a one-piece Grain Flow Forged Chromoly 4120 iron with a face thinned to 2.6 mm and a redesigned sole and topline compared with the JPX-919 Forged. It was sold as a 4-iron through gap wedge set with a players' cavity profile and offset running from 0.150 inches down to 0.091 inches. Lofts were strengthened by one degree through most of the set relative to the JPX-919 Forged, giving a 31-degree 7-iron and a 45-degree pitching wedge, which is still two degrees weaker than the JPX-921 Hot Metal. Lofts, lies and lengths listed are the men's standard steel-shaft build.

Finding a used set
The Mizuno JPX-921 Forged 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.

- Swing weight is omitted because published tables give it as a regular/stiff pair (D1/D3 in the irons, D2/D4 in the wedges) rather than a single value. The gap wedge length is listed as 35.25 inches by 2nd Swing and 35.5 inches by TGW; 35.25 inches is used here to match the rest of the JPX series.
