Mizuno JPX 921 Vs. Taylormade P770 Irons Comparison Overview

Taylormade and Mizuno have released some of the most desirable irons of our time. Both manufacturers continue to innovate and lead the pack in terms of their research and development.

Every year, it seems like they are coming out with some new, brilliant technology.

This commitment to innovation is evident in the Mizuno JPX 921 forged irons and the Taylormade P770 irons.

The two sets have some important parallels and some important differences so to help you sort through them all, we’ve put together the following comparison overview.

Mizuno JPX 921 Irons Overview

With the Mizuno JPX 921 Forged irons, you’re really paying for the advanced material that they are made from.

One thing that you will notice after hitting a few shots with any of the Mizuno JPX 921 forged irons is the strength and resilience of the face.

That comes from the grain flow forging process using chromoly that Mizuno has become known for.

Chromoly is incredibly strong and with the Mizuno JPX 921 forged irons, you get extreme consistency across the entire face because these are one-piece forged irons.

It’s really hard to beat the feel of these irons.

However, they sport compact heads and a muscle back design so high handicappers beware: these irons may be difficult for you to get used to.

Taylormade P770 Irons Overview

The Taylormade P770’s also have a forged construction but somehow feel more wieldy in the hands.

That’s probably has a lot to do with the hollow body design of the heads. Since these are hollow body irons, Taylormade was able to insert their urethane foam into the heads which adds to the soft feel at impact.

Like the Mizuno JPX 921 irons, the P770’s are muscle back irons. We actually like the more streamlined muscle back design of these irons compared to the Mizuno JPX 921 forged irons.

However, the P770’s are about as forgiving as the Mizuno JPX 921’s; which is not very much.

Still, we feel that the Taylormade P770 irons will look pretty good at point of address to mid and low handicap players.

Another big difference was the slightly larger sole of the Mizuno JPX 921’s compared to the P770’s.

The Mizuno JPX 921’s had the better feel with fewer moving parts and provide more consistency. The P770’s are lighter and have a sleeker design overall.

Mizuno JPX921 First Impressions

The JPX921 irons couple incredibly sleek looks at address and with an amazing forged feel.

The Mizuno JPX921 Forged irons have a beveled trailing edge on the sole which smooths out turf interaction. This coupled with the obvious amazing feel from the grain flow forging process makes these irons so pleasing to swing.

The blades of these muscle back irons are pretty compact and there is a part of the back area that has been milled to increase stability and thin out the back wall a bit. These irons also feature the notorious  chromoly construction which contributes to the soft feel.

Taylormade P770 First Impressions

The first thing you will notice is the clear line of site you have to the ball thanks to the limited offset of these irons.

When you first take a look at the Taylormade P770 irons, you don’t automatically think distance.

That’s because they lack most of the visual features of your typical distance irons.

You will probably think that they are great for accurate approaches, shaping shots and higher spin rates; but not so much for distance.

After you take your first swing with 7 iron though (featuring 33 degrees of loft) you will be able to feel the speedy engine behind these irons which have a softer feel.

The Taylormade P770 irons feature a forged hollow body design that allow for maximum face flex.

The face is forged from 4140 carbon steel and is wrapped seamless style around the body which is also made from carbon steel.

You also get a whopping 46 grams of tungsten to fortify the sweet spot and launch the ball high and with workability.

Just because these are mid to low handicap player irons doesn’t mean that Taylormade has left out additional forgiveness features.

For instance, the ICT technology is progressive throughout the set which means that you get an optimized sweet spot location as you work down the set.

The Taylormade P770 have to be swung to believe. They look like players irons but they also have a lot of forgiveness features.

Not quite as long as some other irons but plenty else on offer with the P770’s.

Who Are The JPX 921 Forged Irons For

For starters,  these irons would work great for any player who wants to emphasize precise feedback and feel as a low handicapper and beyond.

We can’t emphasise enough that you’re not going to want to invest in these irons if you’re just starting out with golf. These are performance irons through and through for the better players.

While the JPX921 Forged irons do give impressive distance the compact heads and points of design emphasis will be lost on beginners who will struggle to find the sweet spot consistently, if they don’t find the higher price point off putting enough already.

The JPX921 irons did play more accurate around the pin and were more forgiving than many forged Irons with their toe bias weighting.

Perfect for single digit handicap pin hunters around the world.

The JPX921 Family

The JPX921 Forged irons are joined by the JPX921 Tour and JPX921 Hot Metal irons.

The JPX921 Tour irons produce surprisingly straight shots for tour-grade clubs. They have sleek, compact heads and feature the same grain flow forging construction.

The JPX921 Hot Metal irons are the most forgiving in the family with a Cup Face design that preserves ball speed around the perimeter.

Who Are The Taylormade P770 Irons For?

The Taylormade P770 are for mid to low handicappers who are looking for a good combination of feel, distance and workability.

If you want to take a step up in terms of performance from your Big Bertha’s, P790ti’s and other distance irons, the Taylormade P770 irons would be a good next logical step.

They are a great combination of workability and shaping shots without compromising much in either department.

They produce mid-level range spin which can be a problem in the long irons but is a benefit in the shorter ones.

So they’re certainly not perfect but they strike a good balance between distance and accuracy.

If that sounds like the kind of iron set you need then you should definitely check out the Taylormade P770’s.

The P Series From Taylormade

The P series of Taylormade irons run the gamut from pure distance to pure feel to pure accuracy and everything in between.

While only the P790 irons can be considered more distance irons, the P series is mostly focused on the performance that mid to low handicappers need on the course.

In fact, every other line of irons in this series rocks a mid-level range spin so you can control roll around the green and on approaches.

The P7MB and P7MC iron sets offer the highest degree of accuracy and workability if that it your aim.

Distance: 90/100

Accuracy: 95/100

Forgiveness: 91/100

Feel and Control: 96/100

Value: 90/100

Overall Rating: 94/100
