About the Mizuno JPX-800
The JPX-800 is the iron that established Mizuno's JPX line as a distance range. The 4 to 7 irons use the Max COR Hot Metal face over a pocket cavity with an external power bar; the 8-iron through pitching wedge move to a deep pocket cavity, and the gap and sand wedges to a solid power-bar design. Lofts are strong for the period — 32 degrees at the 7-iron and 44 at the pitching wedge — and offset is heavy, 0.209 inches at the 4-iron. The set starts at a 4-iron and runs to a 55-degree sand wedge.

Finding a used set
The Mizuno JPX-800 ran from 2011 to 2013 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.
- golfclubspec.com Mizuno JPX-800 entry (iron_results.php?id=263), dated 2011 — loft, lie, length, offset and bounce for the 4-iron through sand wedge, and the Dynalite Gold XP / Exsar iS4 stock shafts.
- intheholegolf.com Mizuno JPX-800 Iron Set product page — reproduces the identical chart club for club and adds the set construction detail (Max COR in the 4 to 7 irons, deep pocket cavity in the 8-iron to pitching wedge, solid power bar in the gap and sand wedges) and the Mizuno/Golf Pride M-21 grip.
