About the Mizuno JPX-800 Pro

The JPX-800 Pro is the forged, compact partner to the cast JPX-800 in the first JPX generation, unveiled in autumn 2010 and a 2011 Golf Digest Hot List gold medalist. It is Grain Flow Forged from 1025E carbon steel with an undercut cavity that thins the face for speed, and a Triple Cut sole. Lofts sit between the MX line it replaced and the distance-first JPX-800 — 33 degrees at the 7-iron and 45 at the pitching wedge — with a moderate offset ladder from 0.171 inches at the 3-iron. The catalogued range is 3-iron through a 50-degree gap wedge. Figures are the men's standard steel build.

Finding a used set

The Mizuno JPX-800 Pro ran from 2010 to 2012 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.
