Mizuno announces new JPX 919 Tour Forged irons are coming August 29 (via cryptic Twitter post)



While cryptic, it does appear Mizuno is announcing via Twitter that its new JPX 919 Tour irons are coming on 8/29/18. One would have to assume that means they will be launched on 8/29, not actually hitting retail on 8/29, but that remains to be seen.

We recently spotted a number of new irons on the USGA conforming list, including the JPX919 Tour irons pictured above, JPX919 Forged and JPX919 Hot Metal irons from Mizuno. So it’s likely that the JPX 919 Tour Forged irons won’t be alone in the JPX 919 family when they hit retail.

The JPX 919 Tour iron specifically pictured in the Tweet above seems to be the replacement for Mizuno’s JPX 900 Tour irons that Brooks Koepka used to win this year’s U.S. Open and PGA Championship. Learn more about the original JPX 900 Tour design from Mizuno’s Chris Voshal on our Gear Dive podcast.

Diving a bit deeper into the picture from Mizuno’s Tweet, it appears the JPX919 Tour irons will utilize Mizuno’s familiar Grain Flow forging, and will be made from 1025E; that’s based on the hosel stamping that says “GF Forged HD 1025E.”

Stay tuned for more info from Mizuno.

    If Mizuno follows their recent trend, the JPX 919 Tours will be RH Only.

    Every detail has been intricately executed into a cutting edge design. Sweet! Looks like long irons will have small cavities for improved launch. I’m sure they will transition to solid in the short irons. Can’t Waite to try! Glove box fund is building.

    Miz grain flow forged irons are the sweetest, most buttery, exciting irons on the market.

      I would love to get my fingers on those Miz irons and caress the curves and crevices in the cavity back…. OoOoOoh 😛

    Is there a USA made brand of hot forged irons… or are they all made in Japan, China, Taiwan, Bangladesh…???

      Don’t know of any forging in USA but NCW mill in USA

      These Miz 919s are so beautiful I can’t wait to get my trembling hands on them. Perfect design in a perfect forged club = soft buttery feel. Only 10 days of suffering before I can buy them.

    Im a big fan of Mizuno irons, they typically have a nice balance of performance and beautiful design. These 919 irons, however, look pretty goofy. I don’t get it.

      I wouldn’t say goofy but they look more like something srixon would release with the sharp angles. Not a fan. I liked when they had soft angles like the mp32,64,68,69,4,5.
      It seems to go against their tradition but I understand all companies change.

    But why 919? Why not just carry on and call it 950? crazy naming

      Nope – ignored again – 919 forged though

    If the roadrunner is a cut-out, that’ll make for some cool paint fill options. Gotta say that cavity looks like a pig to clean.

    Not a fan of these at all.

    I love the look of the cavity back design… it reeks with reiteration of Mizuno engineering and ne plus ultra design.

    But does Koepka switch after winning multiple majors?

    • gunmetal

      Aug 17, 2018 at 10:56 pm

      If he were on staff with Mizuno there’s been a slight miniscule possibility of switching. Given that he’s not a Mizuno staffer I’d say no chance at all.

    I play the 900 tours, and they are the best irons I’ve ever hit…can’t imagine how they are better?

    • shane

      Aug 19, 2018 at 3:02 pm

      It’s all about the design of the cavity back with it’s curves and crevices…!!!
