Ping i540 Vs Mizuno JPX 925 Forged Irons Comparison And Performance Review

TL:DR Overview
The Ping i540 and Mizuno JPX 925 Forged are both players distance irons aimed at mid handicappers who want explosive distance without giving up control or the ability to hunt pins.
The i540’s were faster, longer and with better stopping power despite spinning less than the Mizunos in our testing.
The Mizuno JPX 925 Forged had higher launch, more spin and the softer buttery feel but gave up a few yards to the Pings.
Both are excellent choices but will suit slightly different golfers depending on what you value most.

Ping i540 Irons Overview

The Ping i540’s are the replacement for the popular i530’s and they’ve managed to squeeze even more performance while keeping that sharper players look.
These are hollow body players distance irons with a thinner face that’s 9% thinner than the previous model, and the inR-Air Technology sits behind the face which is a pressurized air pocket that dampens vibration and improves sound while letting the face flex for more distance.
The forged C300 maraging steel face is welded to the Hyper 17-4 stainless body with 24 grams of tungsten sitting low in the sole of the 4 to 7 irons to lower the center of gravity for faster ball speeds and higher launch.
The covered cavity construction keeps everything looking clean with a chrome plated ABS cap and the Hydropearl 2.0 finish helps with consistent launch and spin in wet conditions.
The i-Beam technology adds internal support for structural stability and refined acoustics which helps filter out the harsh frequencies.
They’ve also got a slightly longer blade length for higher heel to toe MOI and more forgiveness on mishits without looking chunky at address.
The sound is distinctive, quite high pitched and loud at impact but the feel is pleasing with good feedback on center strikes and clear distinction when you miss the sweet spot.
Mizuno JPX 925 Forged Overview

The Mizuno JPX 925 Forged irons are all about blending classic forged feel with modern distance technology for the golfer who refuses to give up that buttery soft impact.
The long irons are forged from Chromoly 4120 for strength and ball speed while the short irons use 1025E Pure Select Mild Carbon Steel for maximum precision and that famous Mizuno soft feel.
The Contour Ellipse multi thickness face spreads ball speed across the entire face so even off center hits fly pretty true with good distance.
The triple cut sole improves turf interaction making these versatile from all kinds of lies and around the greens too.
They come in Satin Chrome and Forged Black finishes with a thin topline and minimal offset for that classic players look that inspires confidence at address.
The Grain Flow Forged HD process gives precise forging and superior feel especially on pure strikes which is what Mizuno is famous for.
The lofts are strong with a 7 iron at 30 degrees for added distance but the flight is controlled and doesn’t balloon like some distance irons do.
The feel is soft and buttery, proper forged sensation that lets you know exactly where you caught it on the face.
Overall Comparison Ping i540 Vs Mizuno JPX 925 Forged
The Ping i540’s were faster and longer in our testing with slightly better stopping power despite having less spin than the Mizunos.
The i540’s had faster ball speed and covered more ground while still providing steep enough descent angles to hold greens.
The Mizuno JPX 925 Forged launched higher and spun more with steeper descent angles for excellent stopping power but gave up a few yards in distance.
The big difference is in feel and sound. The Mizunos have that classic soft buttery forged feel that Mizuno is famous for while the Pings are more hot and powerful with a high pitched sound at impact.
If you’re a feel purist who wants blade like feedback but needs modern distance numbers the Mizuno JPX 925 Forged is the unique offering here.
The soft sensation on strikes is as good as any forged blade despite the launch monitor showing serious distance.
If you need help with launch and want explosive distance with good stopping power and don’t mind a firmer more powerful feel the Ping i540 is the technical powerhouse.
The Pings also offer more forgiveness with the tungsten weighting and longer blade length stretching the sweet spot more than the Mizunos.
Both sets allow for mixing and matching with other models in their ranges. The i540 sits between the i240 and G440 while the JPX 925 Forged bridges game improvement and true players irons.
The Mizunos will suit golfers transitioning from game improvement irons who want a forged compact iron with a bit more forgiveness than a traditional blade.
The Pings will suit mid to low handicappers chasing every bit of distance who still need stopping power but don’t want chunky looking clubs in the bag.
Both are excellent options so always best to get a fitting to see which suits your strike pattern and preferences better.

Ping i540 First Impressions

The Ping i540’s are the follow up to the hugely popular i530’s and the first thing you notice is how much cleaner these look at address.
We have a thinner top line and a more refined profile that better players are going to love. These don’t look like chunky distance irons, they look like proper players clubs. The big talking point is the new inR-Air Technology which is basically an air bag sitting inside the cavity that filters out the unwanted frequencies. The result is a powerful feel that’s a bit firmer and hotter than the i530’s. Its not quite as buttery but its still really satisfying at impact. The face is forged maraging steel that’s 9% thinner than before and it flexes like a metal wood for serious ball speeds. We also have tungsten weighting in the 4 through 7 irons which keeps the COG low for easy launching. Distance gapping was really consistent throughout the set and the wedges are shaped beautifuly for a distance iron. You can actually control these around the greens which is rare in this category. The offset in the long irons might put off some better players but it will help others square the face up more consistently. Overall these are some of the best players distance irons on the market right now.

Who Are The Ping i540 Irons For?
The i540’s are built for golfers who want distance and speed but dont want their irons to look like shovels.
Mid handicappers will get the most out of these clubs but low handicappers who want some extra help will also find alot to like here. The ball speeds are impressive and the stopping power means you can actually hold greens. If you liked the i530’s but wanted something that looked a bit more refined in the bag, these are exactly what your looking for. The feel is a bit different to the i530’s so if you prefer that softer buttery sensation, you might want to test both. But if you want speed, consistency and a players aesthetic, the i540’s deliver. Available in steel and graphite shafts with pricing around £200 per steel iron and £210 for graphite.

Mizuno JPX925 Forged First Impressions

What strikes you straight away with the JPX925 Forged irons is the balance Mizuno have found between that classic forged feel and a bit of forgiveness to keep you steady when you don’t quite hit it sweet.
The midsize cavity back is aimed squarely at the pro to mid handicap crowd who want precision but also playability. The triple cut sole really helps the club glide through all sorts of lies and turf conditions which is a nice touch for links or softer courses.
The forged Chromoly face on the longer irons gives you that explosive ball speed, while the shorter irons forged from mild carbon steel offer plenty of feedback for shape and control. It all looks great in the bag and at address too, an all around impressive club set.

Who Are Mizuno JPX925 Forged Irons For?

These irons won’t suit the beginners or the really high handicappers looking for maximum forgiveness. But they are spot on for the mid to low handicappers who want a forged iron that still lets you work the ball around the course.
The balanced weighting means you get good forgiveness but also can shape shots and feel exactly what’s going on. If you want a bit of the Mizuno magic, that smooth buttery feel, but still want to stand up to some variety in lies and conditions, these fit the bill nicely.
Perfect if you don’t want harsh blade-like small heads but still want something that offers control and precision.
