Indeed, that is precisely what you get with the Mizuno JPX921 and the MP-20 HMB irons. However, there are some key differences between these two set. If you have the money to splurge on either of these iron sets you should know all the facts before you make a decision.
In the following article we will give you the background for both of these sets and share with you the results of our side-by-side testing.
Mizuno JPX921 Forged Irons Overview
The Mizuno JPX921 Forged irons were released in September of 2020 and they immediately fell in line with the rich heritage of past Mizuno models.
One of the things that makes Mizuno such a renowned name in golf is their grain flow forging. Grain flow forging follows the natural pattern of the solid piece of metal. It doesn’t detract from the strength of the metal but actually reinforces it by going along a uniform grain pattern.
The Mizuno JPX921 Forged irons feature this process of forging as do many previous and subsequent Mizuno models.
Mizuno MP-20 HMB Irons Overview
The Mizuno MP-20 HMB irons actually came out before the JPX921’s. They were released in the fall of 2019.
The Mizuno MP-20 HMB irons were designed as an innovative set of hybrid irons. They took the idea of replacing the longer irons with hybrids and followed it through the entire set.
Who is Each Set Best for?
For starters, both of these iron sets would work great for any player who wants to emphasize precise feedback and feel.
Let’s just start by saying 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. While the JPX921 Forged irons do give impressive distance the compact heads and points of design emphasis will be lost on beginners.
Instead, both of these iron sets would be most beneficial for mid to low handicappers looking for more performance from their scoring irons.
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.
The MP-20 Family
The Mizuno MP-20 line of irons also includes the standard MP-20 and the MP-20 MMC irons.
The Mizuno MP-20’s are your straightforward muscle back irons. They were forged from a single piece of mild carbon steel which lends incredible stability and feel to these irons. The MP-20 MMC irons feature a hybrid cavity/muscle back design.
This design helps make these the more forgiving irons in the family. They play straight and longer than normal on off-center strikes.
