Mizuno JPX919 Hot Metal Pro Irons Review

50 Words or Less

The Mizuno JPX919 Hot Metal Pro irons offer forgiveness and ease of play with minimal offset.  Ideal as a long iron replacement for the better player.


Whether in their MP line or the JPX series, Mizuno has been offering golfers tremendous opportunities to create their own blended sets.  Whether you need more forgiveness, ball speed, or higher launch, you can mix and match their models to suit your game.  With the JPX919 Hot Metal Pro irons, Mizuno is adding a very in-demand option to their fitting matrix: a hot, forgiving iron with minimal offset.


As you would expect, the JPX919 Hot Metal Pro looks like a cross between the JPX919 Hot Metal and the JPX919 Forged.  The top line is significantly slimmer than the Hot Metal, but a bit thicker than the Forged.  Sole width is similar to the Hot Metal.

What surprised me is how little offset there is.  The Hot Metal Pro actually has less offset than the Forged.  It even has less offset than the JPX919 Tour in the 7-PW.  If you’re the player who’s been searching for a forgiving iron with minimal offset, the Hot Metal Pro may be perfection.

Sound & Feel

Though the look of the JPX919 Hot Metal Pro is more player-ish, the sound and feel are not.  Impact is loud, and the feel borders on hard.

Everyone in your group will know when you’ve mishit this club – you’ll hear a “clank” instead of the “click” of a centered shot.  Feedback through the hands is vague.  Big misses can be located, but small misses all feel similar.


Since its inception, the Hot Metal name has meant long and forgiving.  That remains true with the new Pro version.

Despite the decreased offset, the JPX919 Hot Metal Pro plays similarly to the standard JPX919 Hot Metal.  The ball launches on a strong trajectory with plenty of speed.  These irons also offer plenty of forgiveness.  Small mishits won’t lose more than 10 yards of carry, and thin shots will be lifted onto reasonable trajectories.

The Hot Metal Pro irons have the same lofts as the standard version, which is to say they’re rather strong.  If you’re using these in combination with another set make sure you’re getting the right clubs.  You may end up carrying two irons marked “4” or “5,” but I doubt you’ll care when you’re taming long par 3s.


With their pleasing looks and ample distance, it’s no surprise that the Mizuno JPX919 Hot Metal Pro irons have already been adopted on the PGA Tour.  Whether you’re searching for an entirely new set or just some long iron replacements, these are worth taking a look at.

  1. I just got fitted for these at Club Champion last month. They’re the first Mizuno clubs I’ve ever owned. The feel on them is really good. The sound doesn’t seem as loud to me as you described. But I was also using the Callaway Steelheads and the RocketBladez before these and both of those have a very distinct thwack that lets everyone know you hit it in the center.

  2. Sound and feel are certainly relative. Just got fitted for a set of these today and the feel between the 919 Forged and these clubs is very similar. I didn’t get the “clank” sound either. I was, frankly, shocked at how much I enjoyed hitting these. As a 9 index, I’m thrilled with these clubs.

    Forgiveness wise how does this compared to the hot metals,? I know lofts are same so I assume the distance is equal

  4. How would you compare these irons to the Ping G400 and Titleist 718 AP1 in terms of forgiveness and performance?

  5. Utah Duffer

    I just received my new set of these after a recent fitting at Club Champion also. Never thought I’d end up with a set of Mizuno irons, but they performed the best for me of all I tried. I’m a high handicapper and they seemed to compensate for some of my swing flaws and on average I’m 10-15 yds. longer per club which has to help. Really pleased with these so far.

    I banged around for many years with my ping I5’s love them things, now retired I needed something to carry me through my retirement year’s. Just got fitted with my hot metal pros I am one happy guy, they perform like they said they would and look great in my hand. Thank you Mizuno!

  7. Thanks for the great review on these Matt. I’m a 0 hndcp, low spin player (97mph driver SS) and I’m looking for a players distance iron I can get decent higher peak height and land angle with. Are the Hot Metal Pro with a higher launch shaft (I think c taper lite is standard steel offering) the best ones in this category to look at….or would you recommend another based on what I am looking for – higher launch and peak height? Thanks for the help!

      If you don’t mind the bulk of the Hot Metal Pro, it could be a contender. If you want a players iron (i.e. minimal offset, not too bulky), the best route to higher launch is going to be finding the right shaft. If you work with a good fitter, they can get you into something that will perform as you need.



  8. Just fitted for a set. I didn’t get the loud impact noise or the harsh feel you reported. In fact I was pleasantly surprised by both compared to the other cast clubs I hit. As was said this is subjective, these are replacing my Ping i200s, irons praised for their feel which feel dead and hard as rocks compared to the Mizunos.

    Distance, feel and forgiveness is exactly what I was looking for, cant wait to put them in the bag
