Rough and Recovery Shots:

  • Playability: The irons cut through tough lies without losing much control.
  • Feedback: Even when I didn’t hit perfectly, I could feel it, which helped me adjust my swing on the next shot.

Landing Window and Angle:

  • Observations: I noticed a balanced landing angle, preventing the ball from coming in too hot, which is often seen with distance-focused clubs.
  • Consistency: I liked how similar each shot’s carry distance was, which boosted my confidence in these irons.

Throughout my game, the predictability and feedback from the irons were good. I tried a range of shots with confidence, from strategically placing the ball on the fairway to directly targeting the pin. The valuable feedback on slight mishits also helped me maintain a consistent performance throughout my round.

My Test Stats 

I conducted numerous sessions with the Mizuno irons using the SkyTrak+ and compiled data to assess my performance. Here is a detailed analysis of the findings:

ParametersMy Stats
Ball Speed123.4 mph
Clubhead Speed92.7 mph
Launch Angle18.2 degrees
Spin Rate7570 rpm
Descent Angle49 degrees
Peak Height103.5 ft
Carry Distance175.2 yds

A ball speed of 123.4 mph and a clubhead speed of 92.7 mph indicated a solid transfer of energy at impact, reflecting the quality construction Mizuno is known for.

The 18.2-degree launch angle helped me achieve a desirable trajectory on my shots, which combined with the high spin rate of 7570 rpm, gave me control over ball flight and landing. 

When I played, the ball came down at a 49-degree angle, which was sharp enough to make sure it didn’t roll too far after landing on the green.

What I liked about JPX 923

  • Accuracy: Mizuno JPX 923 Forged Irons ensured that each swing led to dependable lengths and pinpoint accuracy.
  • Feedback: They struck a great harmony between a soft feel at impact and the right amount of bounce, while also clearly indicating when a shot isn’t hit perfectly.
  • Dispersion: With their design, these irons allowed for controlled shot dispersion and offered the flexibility to shape their shots on the course.
  • Aesthetics: They have a compact and stylish look with minimal offset and clean lines that appealed to me.

  • Innovations: The irons incorporated innovative technologies, such as the HD Grain Flow Forged process and Harmonic Impact Technology, which offered improved sound and feel. Additionally, precise back milling ensured consistent ball speeds, while a V-Chassis provided enhanced stability.
  • Shaft Performance:  The AMT design, which progressively increases in weight from the long irons to the short irons, helped me to achieve a lower launch in the short irons and a higher launch in the long irons, optimizing performance across the set.
  • Spin: I found that the club generated a high enough spin rate to hold greens effectively, which was particularly noticeable on approach shots where stopping power was crucial.
  • Launch Angle: The launch angle with these irons was consistently high, helping me to achieve greater carry distances while still maintaining control, which was beneficial for both long and short iron play.

What I didn’t like about JPX 923

  • Suitability: While the forgiveness is good but not enough as compared to some other irons.
  • Design: The sleek and compact design was visually appealing, but as I transitioned from bulkier irons, it required some adjustment time to get comfortable with the new feel.


We would recommend Mizuno JPX 921 Forged Irons and Mizuno JPX921 Hot Metal Pro that you can consider the below as worthy alternatives to the Mizuno JPX 923 Forged Irons.

1. Mizuno JPX 921 Forged Irons

Designed for low-to-mid handicap golfers, they offer a balance of feel, forgiveness, and distance. The stability frame and thicker cavity pad ensure that even though these irons give you the workability you’d expect from a forged club, they don’t punish mishits as harshly.

2. Mizuno JPX921 Hot Metal Pro

These irons are well-suited for mid-handicappers seeking a sleeker profile without stepping into the challenging territory of player’s irons. They stand apart from the JPX 900 series with tighter lofts and a thinner top line. 

My Take

The Mizuno JPX 923 Forged Irons are a great fit for mid to low handicappers who want both precision and distance control. The Harmonic Impact Technology provides satisfying sound feedback when the ball is hit. In short, these irons offer a quality, high-performing option for dedicated golfers in search of a dependable, premium forged set.
