As someone who grew up playing Mizuno T-Zoid irons as a kid, there are two attributes I’ve come to expect from the equipment manufacturer – durability and reliability. There’s never been a need for flashy marketing campaigns or eye-catching colors. You know what you’re getting with a Mizuno product, and that’s generally enough for loyalists to part with their hard-earned cash.

What makes Mizuno’s latest JPX925 Hot Metal such an intriguing product is how it blends classic Mizuno looks with game-changing technology screaming at you from under the hood. This product has routinely pushed the performance limits of what a Mizuno iron is can do.

of Mizuno JPX925 Hot Metal Pro it’s the best player it offers in a lineup consisting of three models (Pro, Standard, and HL), and it’s the one that most closely matches my Ping i230s in terms of blade length, offset, and topline. At 28 degrees, the Hot Metal Pro 7-iron had an immediate advantage over my i230 33-degree iron, so I expected there to be a noticeable difference in spin, launch, ball speed and distance.

My hypothesis was borne out during testing as the JPX925 Hot Metal Pro ended up nearly 7 yards longer than my players with a lower launch angle (delta 2 degrees), spin rate (delta 1200 rpm) and maximum height (delta 5 yards). . Some may sing of loftier lofts – some call it “loft-jacking” – but I’ve come to realize that there are golfers out there who generate a lot of spin and benefit from the change in loft.

Something else that impressed me was the overall distribution model produced by Pro. In most cases, I try to match the specs of whatever club I’m testing with whatever is currently in the bag. However, I was very excited to test the Pro, in particular, so I did the initial testing with the stock build, which wasn’t too far from what I’m currently using.

As you’ll see above, Pro went ahead with a very custom set of irons in the distribution department. Only one ball crossed the center line – I try to keep whatever is left of the center – which is impressive considering it didn’t have my medium grip (with extra wraps of tape) or extra weight on the toe. I was so impressed that I plan to run additional testing with my current build specs to see if the numbers can be improved.

The overall feel is what many have come to expect from Mizuno’s Chromoly head material: it’s fast, strong and responsive. The sound bar in the rear cavity did a good job of keeping the sound within a range I found pleasant. It’s not silent, but it’s definitely not loud. Goldilocks would be a fan.

conclusion: I need to do some work to see if I can increase the launch and spin speed, but the iron checked a lot of boxes for me right out of the gate. The compact profile and minimal offset suit my eye, and I appreciate how Mizuno keeps colors and graphics to a minimum in the JPX line. I’m not looking for flash, just performance.

The overall consistency is also what I have come to expect from a Mizuno product. I didn’t hit a squirrel in the first seven swings I took, and that continued throughout the rest of the session. The multi-material face construction helped keep bad swings in a playable range and rewarded center hits. It’s exactly what you want to see from a new offering.
