It’s fair to say, the 2025 season belonged to the Srixon ZXi iron range. Heading into the 2026 season, Mizuno are looking to re-establish itself as the best player iron on the market.

This has coincided with the release of the new Mizuno M13 irons which are to replace the MP-243 irons. But do they deliver that classic Mizuno feel to reclaim the top spot? Find out in our full Mizuno M13 irons review below.
NCG Summary
NCG SUMMARY
The Mizuno M13 irons are a superb option for confident ball strikers. The short irons offer exceptional control, the mid irons provide an increase in speed and launch, and the long irons produce some of the most playable clubs Mizuno has ever created in a players’ iron.
These irons aren’t designed to hide mishits but they do offer some stability off poor shots.
PROS
- Feels like a Mizuno should
- Plenty of spin and a high launch
- Clean, classic look
CONS
- I don’t love how you can begin to see the back of the head at address with the longer irons
First Impressions
Behind the ball, the Mizuno M13 irons look how you’d expect. They have a compact, elegant profile with a thin topline and minimal offset. It is very much a traditional player’s iron look.
Although the longer irons do have a bigger club head and a bit of a visual change from the rest of the set. I was able to see the back of the club head in the longer irons at address, which isn’t usually the case with these type of irons.
As far as the feel goes; I had no complaints. They have retained the brand’s hallmark Grain Flow Forged HD 1025E Elite Steel construction in the short irons, which produces the soft, premium sensation that has become synonymous with Mizunos.
NCG Verdict
In terms of performance, although these irons aren’t built as pure distance clubs, they do produce noticeable speed gains in the mid and long irons. I thought the new face construction and slot technology clearly outperform the previous generation, generating higher launch and more efficient ball flight without resorting to stronger lofts.
The technology in question is a 4120 chrome-moly face which is thinner than that of the previous model. Paired with a through-slot cavity behind the face, the ball speed is increased at launch.
Ultimately my data from testing was impressive. My 7-iron delivered around 170 mph ball speed, 160 yards of carry, and 6,500–7,500 rpm of spin, which is all extremely impressive results for a traditionally lofted head.

Even my mishits still showed surprisingly playable launch and descent angles, to help the ball stop on the green more effectively rather than skidding through and off the back.
For a compact set of irons I thought they were very stable. I must admit I didn’t expect them to be going into testing. Although these irons don’t disguise mishits like more forgiving irons do, they still offer more support than what traditional ones like these do.
But, the thing I found the Mizuno M13s truly excel in is delivering a consistent, predictable ball flight. Something that I value above all with my irons is to be able to shape shots from both ways.
Yardage control is excellent, particularly in the scoring clubs, and the long irons remain workable while still offering meaningful launch assistance.
Final Thoughts
They look good and they feel good. This is exactly what I expect to uncover when I pick up a Mizuno iron. I was able to experience plenty of control and height on my shots and most definitely stand out as one of the most compelling iron releases of 2026.
I have to say I’m not a big fan of being able to see the head of the longer irons when at address. But generally I don’t really have any major comments to pick up on and that only has to be a good thing.
