Mizuno JPX 921 Forged Irons Review

Mizuno JPX 921 Forge Irons Maiden Voyage

This is Golfer Geeks' Mizuno JPX 921 Forged irons review.

I'm an avid golfer, a 9.2 7 handicap on my way to a 2 (been a 5.6) and frequent tester of golf clubs and equipment since 2015.

I tested the Mizuno JPX 921 Forged (and Hot Metal) irons for two weeks on the course (mainly) and on the range.  

Summary: I've never hit a better feeling iron. "Soft" seems insufficient. They launch high and easily. Produce excellent distance on center contact and don't lose much on off-center contact. They have a high, piercing trajectory. Yet, are easy to flight down and work either direction.

JPX 921 Forged Irons by Mizuno

Mizuno JPX 921 Forged Irons Overview

They combine the playability characteristics of the JPX 921 Tour irons with the game improvement benefits of Chromoly from the JPX Hot Metal irons.

The Chromoly material gives the JPX 921 forged irons excellent feel, distance, look, and forgiveness in a forged iron for the first time. 

Why Consider the JPX 921 Forged irons

I thought my irons - with 1025 soft carbon steel - were soft and felt great. They are and they do. The JPX 921 Forged irons are on a different level.

I've played two rounds with them and I still can't get over it. Don't sleep on their performance. They launch the ball easily, high, and far. But, you can play shots with them too.

The JPX 921 Forged irons are the total package.

My Experience with the Mizuno JPX 921 Forged irons

The first time I hit the JPX 921 Forged irons was on the course. I normally warm up on the range, but it was closed due to excessive soggyness. 

My first shot was with gap wedge to lay up on the first hole - a par 5. I was in light rough and hit it well, but it's hard to tell much from a controlled short shot.

My shot on the long par 3 which followed this hole told me what I needed to know about these irons. 

I had 215 to a back right pin. I was fine with being short in the middle of the green, so I pulled the 5-iron. Which is 3 degrees stronger than my regular 5-iron. I flushed it...

Dead right of the green, but loong. The feeling on that shot was incredible. Don't think I've felt better from an iron. That shot was gone, so I re-tee'd and pulled a 6-iron.

Flushed it - dead right of the green. But, pin high. Same incredibly soft feel on impact. Same powerful ball flight and medium high trajectory.

Now I know why people speak about Mizuno irons the way they do.

The rest of this round and the following round only reinforced my first impressions. I was in lust. 

Review of the Mizuno JPX 921 Forged Irons

Looks: Solid (A)
I'm a big fan of minimal design and elegant lines. The JPX 921 Forged irons have that in spades. I would have thrown in a "+" if the heads were a liiitle smaller. 

Sound/ Feel: A+++++
Best in the biz. Somewhere, there's a distant second place. 

Distance: A+
Plenty, plenty long.

Forgiveness: A+
Exceptional for a player iron

Flight / Playability: A+

Can't ask for better    

Customer Reviews

Pretty universally loved. Some complaints of shipping packaging issues or thin grips. I consider these irrelevant. 

Who are the JPX 921 Forged irons for?

Low handicap: (Yes) Two things might hold you back: 1) Strong lofts 2) Clubhead size
Mid handicap: (Yes) If... you are close to a single digit handicap. The Hot Metals are a better choice, otherwise.
High handicap: (No) Skip these and give the Hot Metals a look.

Our Verdict

You won't hit a better feeling player iron any time soon. Performance is nothing to sneeze at either. 

The JPX 921 Forged irons need to be on your list if you're in the market for new player irons.  

My #1 suggestion is to get your hands on them before you buy. Either at your local golf store or take advantage of Global Golf's Utry trial program. I use it and recommend it.
