Which Mizuno iron suits me?

Which Mizuno irons should I buy? Your guide to each iron in Mizuno's line-up, and who they are aimed at.

Most major brands have five, six or even seven irons in their 2020 line-ups, which shows the importance of having solutions for all golfers, irrespective of ability or personal preference. Choices range from slimline musclebacks to hollow heads and cavity backs, and while some are forged, others have springy faces just like a driver.  

So with such a huge amount of choice out there, we felt it was far too easy for golfers to get confused about which model best suits them. Even golfers who have a good idea of which iron suits them probably don’t realise what they put on the line in terms of ball speed, carry and forgiveness by choosing a set above their station.

So as 2020’s irons hit pro shop shelves, we felt the time was right to show how a brand’s whole iron range compares against each other.

As well as launch monitor data from our pro, we’ve given every iron a forgiveness rating and a handicap guide to spell out simply what sort of players should be considering what sort of models, and why.

Mizuno MP-20 MB iron

Which Mizuno Iron Suits Me?

RRP: £150 per club 

Construction: Forged from a single piece of 1025E HD mild carbon steel 

Who are they for? 

Thanks to the MP family sporting more traditional finishes, they’re likely to appeal to the eye of very good ball-striking traditionalists.

Our data has the MP-20 as Mizuno’s least powerful iron, so if your game demands keeping an eye on speed or distance they’re absolutely not for you. In reality you’re only really a good fit for a set if your game requires shots to be regularly shaped and you aim to feed approaches on to shelves and ledges on a green, which is less than 1% of us, really.

Mizuno JPX919 Tour iron

Which Mizuno Iron Suits Me?

RRP: £135 per club

Construction: Forged from a single piece of 1025E HD mild carbon steel

Who are they for?

Very much a modern blade, the JPX919 Tours have been a big hit for Mizuno – and Brooks Koepka, who uses them unpaid.

A classic, compact head shape with the shallowest of cavity backs to offer a small degree of forgiveness, but still very much a muscleback-style iron. Interestingly, our samples had different shafts in the MP-20 (Dynamic Gold) and JPX919 Tour (Nippon Modus), which from the same 7-iron loft gave very different amounts of ball speed, launch, backspin and carry.

That alone says setting up any set of Mizunos properly requires a decent fitting session.

Mizuno MP-20 MMC iron

Which Mizuno Iron Suits Me?

RRP: £165 per club

Construction: Forged from a single piece of 1025E HD mild carbon steel

Who are they for?

Mixing a traditional head shape with tungsten toe weighting and a titanium muscle means improved forgiveness over Mizuno’s musclebacks.

Our data has the improvement equating to 2% of carry distance drop off, which is really important to above-average golfers when hitting approaches to very tight flags and steeply banked green ledges.

A brilliant compact players iron, that gives up six yards of 7-iron carry to the similar lofted but hollow body and fast-faced MP-20 HMB.

Mizuno MP-20 HMB iron

Which Mizuno Iron Suits Me?

RRP: £180 per club

Construction: Hollow body with forged chromoly steel face and neck

Who they are they for?

From a 7-iron two degrees weaker than Mizuno’s strongest (32° vs 30°) the HMB showed how it’s Mizuno’s strongest iron this year. And it gets to the top of the pile without cutting backspin, height and decent angle to critical levels.

Our test pro recorded his smallest carry distance drop-off with the HMB, too, which proves how its 24g of internal tungsten weight (split between the toe and heel of the 2-7 iron) is doing a great job of controlling drop-offs on mishits.

To some it will be a deal breaker that the HMB isn’t forged from the same material as Mizuno’s classic one-piece forged irons. But if truth be known, our test pro didn’t spot a difference in feel between them until we told him, so many are unlikely to notice.

Mizuno JPX919 Forged iron

Which Mizuno Iron Suits Me?

RRP: £135 per club

Construction: Forged from a single piece of 1025 HD (with boron trace) mild carbon steel

Who are they for?

The JPX919 Forged are just as at home in a serious 14-handicapper’s bag as they are a category one player. A mass market iron and a great choice for golfers who put a premium on “forged feel”, but probably aren’t the most consistent ball striker.

Plenty of golfers will find themselves choosing between the JPX919 Forged, MP-20 MMC, MP-20 HMB and the JPX919 Hot Metal Pro, as all cover an area of the market where lots of golfers think about buying Mizuno irons.

Let us offer some simple rules to help make a decision. MP-20 MMC are players irons, and by that we mean reasonably consistent ball strikers. The JPX919 Forged are for a huge audience, especially golfers who want as much forgiveness as they can get from a forged model, but also don’t want to give up a forged sound and feel to get it. The Hot Metal Pro chases ball speed with a cup face and a slightly bigger head, you give up a forged head to get it, which is exactly the same story as the fast face HMB.

How do they compare - Handicap Guide

Brands hate giving an indication of which handicap of golfer each iron typically suits, as it pigeon-holes their models. We've given each a handicap guide below though to help ensure you buy the set most suited to your ability.

Mizuno JPX919 Hot Metal Pro iron

Which Mizuno Iron Suits Me?

RRP: £120 per club

Construction: One-piece cast from 4140M chromoloy steel

Who are they for?

Last year the Hot Metal Pro was our test pro’s strongest Mizuno performer, but this year it’s been surpassed by the brilliant MP-20 HMB.

With a very solid spread of ball speed, backspin, peak height, descent angle and carry distance though, it’s still a brilliant all-rounder.

Just remember it’s not forged, hence why it costs less than Mizuno’s forged models. In a blind test, though, we reckon many golfers at this ability level would struggle to hear or feel much difference.

Mizuno JPX919 Hot Metal iron

Which Mizuno Iron Suits Me?

RRP: £120 per club

Construction: One-piece cast from 4140M chromoly steel

Who are they for?

Mizuno’s game-improver iron. A deep cavity back, with excellent perimeter weighting, offers good off-centre hit forgiveness, along with a decent sound and feel. But compared to some max game-improvement irons, the Hot Metal is still a beauty to look at.

We had a few questions last year asking why we didn’t give any Mizuno iron a 28-handicap ranking. Our thinking is that, while the Hot Metal is lovely, there are more forgiving models out there which would probably better suit a 28 handicapper.

It’s worth remembering that even as a distance iron the Hot Metal’s 7-iron loft is three-degrees weaker than the strongest on the market (27°). It’s also 1.5° weaker than TaylorMade’s SIM Max and 0.5° down on Ping’s G710, which obviously affects launch monitor numbers if you test them all head-to-head. Worth bearing in mind.
