JPX-800 Irons Review

The Mizuno JPX-800 Irons deliver unbelievable distance and forgiveness in our longest game-improvement iron. We combined our innovative Max COR technology, an ultrathin Hot Metal face and an exotic pocket cavity to provide the extra yards you've been searching for. You're going to be at least a club longer."
—Chris Voshall, R&D engineer, Mizuno USA Golf

"With the perfect balance of forgiveness, distance and feel, the Mizuno JPX-800 Irons Pro features the highest COR ever in a Mizuno one-piece Grain Flow Forged iron. A large cavity is created using a CNC milling process that thins the face to raise ball speeds for maximum distance and optimizes a low, deep center of gravity for increased forgiveness."
—Richard Delvac, senior R&D product designer, Mizuno USA Golf

The Mizuno JPX-800 irons are a big jump into the game improvement category for Mizuno Golf. Sure- they have other irons in this space (MX-1000, MX-300) but most people know and respect Mizuno most for their game-enhancing line of muscle back and blade irons known for their amazing feel and precision. In my opinion there was a big gap between the MX-1000's and the MP lines of clubs and the Mizuno JPX-800 Irons 's a full-fledged jump into that space, providing 8 to 24 handicappers with a truly remarkable option; a club with the feel Mizuno is known for combined with the game improvement qualities desired by many of us like forgiveness and increased distance. I don't want to ruin the rest of my review- but mission (mostly) accomplished!

The standard Mizuno JPX-800 Irons contains a 4I up through a gap wedge, and comes with your choice of either steel or graphite shafts. The Mizuno JPX-800 Irons stock shaft is the True Temper Dynalite Gold XP (available in R300 and S300), while the graphite option is Mizuno's Exsar IS4 (offered only in R flex). The stock grip is the tried and true Mizuno/Golf Pride M-21 58 Round. Of course, all of this can be customized to meet your needs - Mizuno's Custom Club department is only a phone call away. Both Mizuno JPX-800 Irons left handed and right handed models will are available.
