Mizuno JPX 921 Vs. Taylormade P790 Comparison Overview

Mizuno has been a legend in the game with their amazing forging process that produces incredible feel and performance. Taylormade is no slouch either.

With the P790 irons Taylormade has come up with a set that rivals the storied Mizuno JPX 921 forged irons.

But which set would be more beneficial to your game? Sure Mizuno is great but not everyone can spend that kind of money on a set of irons.

Do you really need to fork over so much to improve your game? Find out in the following comparison article.

Mizuno JPX 921 Irons Overview

The Mizuno JPX 921 forged series of irons uses a CNC milling process that imparts excellent spin control and feel.

You really feel the difference in your short game when you play with these irons. The reduced offset makes for much better shot shaping on short approaches and precise spin control.

That being said, the Mizuno JPX 921 irons don’t play as long as the P790’s.

They have the better overall feel though. They are made with 4120 chromoly steel alloy which is a cross between chromium and molybdenum.

This is a highly specialized steel alloy that has a soft feel with very high resilience.

Taylormade P790 Irons Overview

The Taylormade P790 irons have a comparable feel to the Mizuno JPX 921 forged irons but with a few more performance features that will appeal to the everyday golfer.

Like any Taylormade club worth it’s own salt, the P790’s come with the Thru Speed Pocket which helps the face flex more at impact.

This certainly helped us achieve faster ball speeds and more distance. In fact, the P790’s played an average of 9 yards longer than the Mizuno JPX 921.

The P790’s also feature a 4140 steel face insert that wraps itself into the sole of the club head. This makes for much more forgiving shots if you tend to bottom the ball.

These irons are surprisingly light too even though they are made from forged steel.

They felt wieldy in the hands and were overall the more forgiving irons. They also sport a cleaner muscle back design that we really liked.

Both of these muscle back, forged ions will help you take your game to the next level of performance.

But if you want to get to that level with a slightly more tolerable learning curve, we suggest checking out the Taylormade P790 irons.

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 P790 – First Impressions

The first thing to notice about the P790 irons is the compact, forged heads that come in a shape and style that will suit the better players.

Despite the players feel of the irons, they also come packed with technology that will add distance and forgiveness like the Thru Slot speed pocket, speed foam and inverted cone technology which allows more flex on impact.

The forged irons are actually a hollow construction, filled with speed foam which allows much greater distances to be achieved than the original P790’s and the tungsten weighting keeps the CG low for an easy launch for an iron of this type.

The original P790 irons, released in 2017, were definitely for the players but with the remodelling in 2019, these can also be used for mid handicappers looking to test the waters of players irons.

All in all, definitely not for the high handicappers.

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.
