Mizuno JPX923 Irons Comparison 

Good to see you back Jay thanks for the review

Enjoyed the review especially close to home for me. Just had the Mizuno fitting yesterday ( Aust ) and had my heart set on the Pros but walked out with an order for the JPX Hot Metal - HL’s. I’m 62 with a seven iron swing speed average of 76 mph. I could not believe how easy they were to hit and with the Neo stiff pro shaft managed a very central heat signature on the club face where before I was a consistent toe striker. Three week wait now but couldn’t agree more with your review since I’ve just had that very experience 👍🏻🇦🇺

One of the best reviews I’ve seen!👍

So glad you back. Sim looks great!

thanks full in depth comparison ! best on RU-vid

It’s nice to know you have miss hits! 😂 Thanks as always for the time and effort to make these thorough reviews.

I hit the 7 iron hot Metal standard an average of 170 and 3 yards of center swing speed average 75 and I suck at golf but they are on order. Excited about golf again

He's back! Excited to watch this one.

Great content as always Jay and love the new studio. Keep them coming!!!!

Very informative!

Great review - thank you. Just had a club fitting today for new irons. I’ve come away with a set of Mizuno 923 HMP. I was expecting to be directed to the new Mizuno HL. But HMP seemed to get the best results. I’m 64, handicap at 8. Swing speed around 80mph with 7 iron. What still amazes me is the difference the right shaft can make.

Great job and well commented

Impressive. May wait on the Forged series but the HMP looks and produces playable numbers.

Got fitted for the HL and oh my goodness, what a club, with a swing speed of 80-83

I miss your efficiency graphic that shows the red dead zone and the green band across from heel to toe. That graphic greatly summarizes your forgiveness comparisons. Keep up the great work, love your analysis and insight!

Very interesting video, I own a set of 921 HM, looking at forged 923 next year.

I absolutely love your club testing videos. I am in the market for my next set of irons due to my handicap dropping into the single digits and am looking for an increase in launch angle and additional spin. At 64 yrs old, my 7 iron swing speed in ~81. Would it be possible to test at a similar swing speed. I don't think the majority of viewers swing at 90+ mph and it would certainly help us average joe golfers make an informed decision on our next set of clubs. Thanks again and keep the great reviews coming!!

Would love to see a comparison with these and the 223 and the 225

Great review! Love me some Mizunos…I am a little bummed that many RU-vidrs reviewing these aren’t using the speeds they are intended for (the HL specifically). Having someone with a 90+ mph 7 iron swing for comparison is pretty useless for the HL…I’m also a bit bummed people keep referring to them as super game improvement clubs (with the connotation they are for high handicappers/not very good swingers). From watching the Mizuno videos from Mizuno, my understanding for the HL is for better players who may have lost some swing speed over the years and don’t want to go to hybrids throughout the bag. The biggest difference with the HL is they didn’t move the CG as low as possible like the other 923s, because the target audience has slower speed and more forward shaft lean (e.g., better players who have lost swing speed). That’s key because with forward shaft lean, you don’t hit the ball off the bottom of the club face (as your dots indicate). You hit them closer to center on the face. So, traditional game improvement irons that move the CG lower don’t really help the better players who have lost some swing speed since you’re hitting it where the CG isn’t…

Looking at the HMP with possibly a HL tossed in at the 6,5. I have off days with my current Clubs hitting the long Irons. I currently play Ben Hogan but need a little forgiveness. Want to enjoy more rounds when I am not hitting as well!!

Really interesting video, thank you. I’m sure I’m not alone in being overwhelmed by facts and figures, all interesting stuff for a club fitting but for the average golfer I’m sure it’s comparatively meaningless. I’ll be changing irons next spring (13 handicapper at the moment) and what I’d like to be able to see is something that says out the middle the club hits a ball X yards, an 1/2 inch off centre hit drops the distance by y yards, it’s a high/medium/low spinning club and so on. Also, to hear that a club is suited to golfers in a handicap range of a to b, and when you get 3 new clubs like in this review to say where the handicap ranges if each club overlap.To be fair, every channel reviewer on You Tube does much the same, but I find myself getting to the end with no real concise thoughts, just numbers and degrees bouncing around in my head.

Excellent video, would love to see you swing these 3 irons with a sub 80mph swing to really highlight how much more playable the HL is at that speed over the others.

I'd like to see you compare the H L to the Callaway APEX21 DCB. THANKS

Well for the middle of the road golfer it doesn’t really matter which one you have in your hands. It will definitely make a difference in the level of your pocket book. Probably after the proper fitting your probably well off to get the hot metal. Love this club. Not interested in gaining a few yards. Had mine adjusted 2 degree flatter. Happy, happy. Sometimes people just way too deep in the details which results in deeper into the bushes.

Good to see you back and a great review 👍🏻 From those numbers I question whether the HL works, 2deg more dynamic loft but only 1deg of launch. I would like to see HM and the HL tested at the same loft. They all seem very forgiving.

I am using JPX921Hot Metal. I love it! It hits high and stops on the green. I love sound and feel too.

Nice video Jay, is that the new studio? Nice ball pyramid 🙄

Hi Jay loved this review 👍, liked the High Launch for slower swing speeds, mine is 70 with 7iron, love my T300 iron’s fitted with graphite shaft’s, Lovely high launch 👍(could you review T300 vs High Launch JPX) in graphite shaft’s for us slower swing Senior’s, after 7iron go into Rescue’s 6-5-4,Great idea Mizuno with (high launch) Thanks Dickey 9hcp 75year Senior Golfer

Another great video. Can I request a video if possible, Mizuno Pro Fli hi 19° 3 Vs Hot Metal Pro 19° 4 iron?

Er, I've been fitted for my 923 Forged and getting them in 2 weeks? I'm in Thailand but they get them from the US.

I tried a hot metal against my r9. I hit the hot metal on average 19yds further but a lot less spin. To me, that’s a not go because it more than likely won’t hold the greens as good

Excellent video as always, thanks. Mizuno says that the pros are for "low to mid handicap" but in your opinion would it be that stupid for a high handicap player to pick the hot metal pros over the regular hot metals?

My brother got custom fit for JPX923 Hot Metal and they look great, but you really need to be +10 or better Handicapper to hit these effectively. I bought at the same time Callaway Rogue ST MAX OS and they are so much easier to hit. Not saying they are bad clubs just sayin if you want something to hit easy and don't care about shot shaping or have a handicap above +10 you really should look at those..

Great video. You mentioned at 70mph you transition from high launch to hot metal. Is that a 7 iron swing speed or driver ? Thanks

How would your rate these 923 vs the 225 ? other then the stronger lofts on the 923..Thanks...

I have the jpx921’s in your opinion would it be worth it to upgrade to the 923’s

I would love to actually see someone with slower swing speeds, mid handicap hit these. Do you have any buddies that that could do that with you????

They missed the opportunity the change the Hot Metal Pro to something that will be purchased - it's a real shame. I'm a 919 Hot Metal Pro iron set player, but I've bent the lofts weaker -> (PW, 9, 8, 7,6) -> (47,42,37,32,28) - the key being a 32-degree 7-iron (modern standard only slightly strong) but also having a 'normal' 47-degree PW which I love having to make the set playable & gap properly into a normal bag construction. Please Mizuno, if you read this, please for the love of god, give us a set of lofts, in a Hot Metal Pro (love the lack of offset) that are (47,42,37,32,28,24). The reason I think this is so important is all that has happened is the new 923 Hot Metal (slightly strong lofted ) 7 iron has now become 6 iron at 28.5 degrees - what's the f'ing point? I'm a scratch player, had my lofts and lies done at TXG in Toronto as I basically live next door to them - and my (47,42,37,32,28,24) is a perfect bag of lofts that frees up a club to add another hybrid/wood/wedge to help your game. Why as a scratch player do I play the Hot Metal Pros? Bent weaker they have near zero offset and they are deadly accurate, given their stability frame, which from a Strokes Gained perspective is what golf is all about. I switch out the 24-degree 5-iron to an HMB because I do not like seeing the back of the club. The new high launch clubs will be the big sellers - and hopefully, that will convince the designers that they long ago jumped the shark. I don't want to even mention that the new JPX 232 Forged has a 7-iron now stronger than 32-degrees because I will just get upset. Can we please standardize on a 32-degree 7-iron as being that perfect combo of modern lofts meets modern construction - but we still need to build a bag of clubs that hit certain distances? Make 32-Degrees Great Again - otherwise, I will need to purchase clubs from another manufacturer.

Is there a real difference between these and the 921s HM as far as feel goes?

Still using mp-14

Yeah get subscribed for interesting club reviews

Can't you just get the normal hot metal and get the loft adjusted during the build

Please identify your club head speed for this to be useful.

How high????

There jacking up the lofts 28 degree 7 iron! Where is the control and spin? The one with 31 loft is the ugliest. Not for me.

I wish companies would just STOP putting a number on the bottom of the club and just put the loft , that thing isn't a 7 iron it's basically a 6.5 iron . So tired of companies doing the HYPE thing of Distance, when a 7 iron should produce about 7 thousand spin in my opinion, not under 4500 rpm, and having that damn ball just drop out of the sky to make it stop is a dumb idea! I am a HIGH ball hitter and can not hit these new irons as I punch holes in clouds and the ball just falls out of the sky short !!!! Not a fan of this new technology!

the idea that youre hitting a 7 iron 180 is ridiculous. the lofts are jacked nearly 1.5 clubs. youre hitting a 5.5 iron not a 7. i play wilson staff forged, older. traditional lofts. the 5 in that set is 27 degrees and i hit it 195...the 7 iron in these jpx are 28.5 degrees. its a joke. theyre not going any further then traditional clubs, based on LOFT, which is all that matters.
