Mizuno JPX-850 Forged Irons Review

Mizuno JPX 850 Forged (7)

50 Words or Less

The Mizuno JPX-850 Forged iron is a pretty club with more distance than most other players irons.  The feel is harder than expected for a Mizuno with “forged” in the name.

Introduction

“I just want to say one word to you.  Just one word.  Boron.”

Yes, boron.  That’s the big selling point behind the new Mizuno JPX-850 Forged irons.  Mizuno claims that they’ve been working for 6 years to add boron to their Grain Flow Forging process, and the result is an iron that produces more distance than traditional forged irons.

Looks

The JPX-850 Forged is definitely among the better looking irons in the “forgiving players club” segment.  The top line and sole are thin enough to appeal to better player, but they’re not paper thin.  The offset is fairly minimal, and a rounded toe creates a classic appearance.

The cavity is a little busy, but the all-silver color scheme balances that out well.

Sound & Feel

Feel is the thing most golfers associate with Mizuno, and it’s the one area where the I was really disappointed in the JPX-850 Forged irons.  The feel at impact is quite hard.  For a club with “forged” in the name, I expected a much softer feel.

I was also surprised at the lack of feedback from this iron. I hit the JPX-850 Forged back to back with the JPX-850 and the amount of feedback was nearly the same.  With both clubs, shots anywhere near the center feel almost identical.

Performance

Whether it’s the boron, the “Ultra CNC Milled Pocket,” or something else, the JPX-850 Forged irons are long.  In fact, in our testing, they were longer than their SGI brother, the JPX-850.  We found that these produced more ball speed and had lower launch and spin.  All that added up to 9 more yards total (7 carry), on average.

In terms of the forgiveness, the JPX-850 Forged is average for this category.  Slight mishits will still end up somewhere on the green, but you’ll be in bunkers and lakes if you wander too far from the sweet spot.  Mizuno recommends these clubs for 6 to 16 handicaps, and I think that’s right on the mark.  They definitely don’t stand out for forgiveness, but they’re certainly easier to hit than blades.

Conclusion

If you want a club that makes you look like a player, but you don’t want to give up distance iron yardages, the Mizuno JPX-850 Forged irons are for you.  Though the feel is lackluster, the distances this set produces will make up for it in the eyes of some players.

    Matt, Is there is much difference, if any, in performance (feel, forgiveness, distance) between the JPX 850 forged irons and the JPX EZ forged irons? Thank you. Curt.

      Curt,

      I never got the chance to review the JPX-EZ Forged, so I’m afraid I can’t answer your question.

      Best,

      Matt

    Hello Matt, pardon me that was my error. Would you please comment on any differences you’ve found in performance (feel, forgiveness, distance, etc.) between the JPX-850 forged and the JPX-EZ irons? Thank you, Curt.

      Curt,

      The JPX-850 is a decidedly better-looking iron, but it feels firm, similar to the JPX-EZ…disappointingly. The EZ is somewhat more forgiving, but I don’t think it’s a huge difference. Distance is largely a matter of fitting the best shaft and the lofts, so I think they should be equivalent.

      Best,

      Matt

    Hi’ Matt, I’m playing AP2 right now I’m 15 HDC (because my short game sucks) otherwise should be 9 or 10. I’m looking for something easier than my AP2 , just a little bit, not big deal, and i was thinking in JPX 850 forged, make sense?? it will be the same?? worst? any advice??

  5. I recently got a set of these in great condition. They feel like I’m hitting a ball with a sledgehammer, in a good way. Best ball flight and distance I’ve ever gotten out of any iron, including some of the new “distance” irons. I may never let these things part from my bag.

  6. I have played 3 different sets of Mizunos: MP-19, 10 years, MX-23, 8 years, and now JPX-850 forged this past year. I am a lefty. I am a low ball hitter and the JXPs are great with much higher ball flight. I am about a club longer which is partly the stronger lofts. I love the feel of Mizunos and have not noticed that much difference in feel with the JPX 850 forged
