About the Mizuno JPX-919 Hot Metal
The JPX-919 Hot Metal is the cast, distance-oriented member of the 2018 JPX family, built from Chromoly 4140M with a face milled down to 2.0 mm behind impact. It carried a wider sole, a thicker topline and considerably more offset than the JPX-919 Forged, running from 0.230 inches in the 4-iron to 0.102 inches in the wedges. Lofts are materially stronger than the Forged model of the same generation: the 7-iron is 30 degrees and the pitching wedge 45 degrees, against 32 and 46 degrees on the Forged. The stock set ran 4-iron through lob wedge. Lofts, lies and lengths listed are the men's standard steel-shaft build.

Frequently asked questions
What is the loft of a Mizuno JPX-919 Hot Metal 7-iron?

Finding a used set
The Mizuno JPX-919 Hot Metal ran from 2018 to 2020 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.
