Mizuno JPX919 Tour Irons Review

Mizuno’s JPX919 Tour Irons are a more streamlined evolution of the JPX900 Tour irons and promise tour-calibre performance with precision distance control

The JPX range has been a huge success on tour (three majors from Brooks Koepka alone over the past year and a half with the JPX900 Tour) and in pro shops, but it’s two years old now – so they’re being replaced by, in our view, some of the best-looking irons Mizuno has ever made. They’re called JPX919.

The JPX900 Tour was so popular among tour players that Mizuno consulted a bunch of them before attempting any reworking. They produced three different prototype heads and gave them to three top players. Amazingly, all three picked the same proto as their favourite, so there’s no surprise it has become the new JPX919 Tour.

The JPX919 Tour promises tour-calibre performance with precision distance control. It is a more compact, streamlined evolution of Mizuno’s standout JPX900 Tour iron from 2017/18, which helped to re-establish Mizuno’s presence on Tour among both contracted and non-contracted players.

For the first time in the JPX family, Mizuno are using the same 1025 E HD steel found in their MP family. They say the forging process squeezes grain structure more closely together lower in the blade (where shots are hit), which improves feel and feedback.

There’s also a new “open heel” design, which frees up 5g, which is repositioned in the club’s “stability frame”, improving forgiveness and a 10% thinner top edge. A slightly wider, more cambered sole improves turf interaction for elite players and there’s a sleeker, softer, less grainy finish.

Forgiveness levels of the Tour are similar to the MP-18 SC, which begs the question why make both? Well, Mizuno sees two sets of buyers. MP is traditional, shiny and likely to attract golfers who grew up playing Mizuno, whereas JPX is more likely to attract younger golfers, possibly playing Mizuno for the first time. The Tour is a fantastic looking iron; yes, it’s well above the ability of many club golfers, but that’s why there are two more models in the range.

What Mizuno say:

The JPX919 Tour promises tour-calibre performance with precision distance control. It’s a more compact, streamlined evolution of Mizuno’s JPX900 Tour iron from 2017/18, which helped re-establish Mizuno as the iron of choice on Tour among both contracted and non-contracted players.  Grain Flow Forged HD (High Density) from a single billet of 1025E Pure Select mild carbon steel in Hiroshima Japan, the JPX919 Tour offers the softest, purest Mizuno feel yet.

The JPX919 Tour has a compact, clean look over the ball that elite shotmakers crave, with the top edge narrowed by 10% compared to its predecessor to match the grinds most commonly requested on tour. Despite this, it offers surprising stability for a compact players’ iron, delivering tight distance patterns on off-centre strikes courtesy of a frame that is open at the heel to enhance stability and launch, while still producing a tour-preferred vibration and sound at impact.

“The JPX919 Tour’s compact profile doesn’t tell the whole story,” says Jeff Cook, Mizuno’s PGA Tour Manager. “There’s a surprising level of stability and distance control built into this geometry. Its predecessor attracted a new wave of younger tour players into Mizuno irons and made a big impact by winning back-to-back US Open‘s and recording a course record 61 at St Andrews.” 

The JPX919 Tour features a Pearl Brush chrome-plated finish to enhance durability and soften its precise lines in bright sunlight and can be built to a customer’s desired specification as part of a full or split set.
