Honest Comparison of Srixon ZX5 Vs Mizuno JPX 921 By Sportic Media

I was eager to try the Mizuno 921s, but I actually detested them. I’ll give them a pass because I wasn’t playing well when I tried them, but I didn’t think they offered much in the way of forgiveness.

At the same time, I hit the ZX5s and thoroughly enjoyed the flight. Forgiveness and feeling both had good qualities. The only thing about them that I didn’t like was how they looked and how they were a step back from my current irons. 

I might consider using a ZX7/ZX5 combination. For a higher capper like yourself, the ZX5s will be significantly superior to the 921s. They will also present numerous opportunities for development.

The Titleist T200s deserve special mention and should be taken into consideration. They had an amazing feel off the face, and I also thought they were very understanding. Almost identical to the ZX5s, but YMMV.

In this article, we compare the Srixon ZX5 with Mizuno JPX 921 helping you to select the best one of them. So stick around until the end to find out what you’ve been looking for.

The brand-new Mizuno JPX 921 Forged irons are the first set of irons ever made entirely of Chromoly material. The potential for even more speed, which translates to a greater distance, is unlocked by using this special material to make the entire club head.

The JPX921 Hot Metal irons feature the straightest ball flight Mizuno has ever produced, along with adjustable landing angles and the company’s fastest ball speeds ever.

The JPX921, the third generation of Mizuno irons to use Chromoly’s durability, has the most complex face geometry to date for more clubface energy. For a more compact profile with a smaller offset, select the more professional version.

One of the four new models that pay homage to the players’ eye-pleasing appearance is JPX 921 Forged. The small muscle-cavity blade JPX 921 Tour is at the top of the talent pyramid. It comes after the JPX900 Tour and JPX 919 Tour designs’ successful tour rotation. The JPX 921 Tour utilizes Mizuno’s HD technique from earlier designs to concentrate the grain in the center-hitting area for a better feel. It is forged from the company’s 1025E carbon steel.


For whom?

The category of players’ distance irons includes the Mizuno JPX 921 Forged irons. When placed down by the ball, they fit the preference of the better golfer thanks to their compact shape and sleek lines.

These forged irons are more forgiving due to a redesigned Stability Frame and a thinner, hotter face that helps increase distance. The JPX 921 Forged model is ideal for golfers who prefer a smaller profile but still need assistance with distance and forgiveness.

What handicap should play JPX 921 forged?

Any golfer with a handicap of around 11 or less, in my opinion, can use the Mizuno JPX 921 Forged irons. The Mizuno JPX 921 hot metal is intended for who? Better mid-handicappers and even low-handicappers who don’t mind larger clubheads or a bit more forgiveness can consider the Mizuno JPX 921 Hot Metal irons.

The Srixon ZX5 Irons Are Made for What Handicap?

When compared to the ZX7 irons, the Srixon ZX5 irons are more suited to players with greater handicaps. However, the business asserts that those with low disabilities can use them just as well. The firm seems to be striving to create a “jack of all crafts” type of set with these irons. However, based on our testing, we believe that mid-handicappers can benefit from the Srixon ZX5 irons.

While low handicappers will undoubtedly appreciate the forged design and larger grooves in the long irons, and high handicappers will benefit from the cavity back, mid handicappers will gain the most from the performance of these irons.


How does it looks?

The ZX5 irons’ resemblance to the ZX7s (read the entire review HERE) was one of the first things I noticed about them. The ZX irons feature a more uniform appearance than the previous generation Z585 irons, which had a distinguishing black elastomer around the cavity’s edge to set them apart from the Z785.

Srixon ZX5 vs Mizuno JPX 921

Your game is controlled by a Srixon ZX5. A small amount of torque and spin can be used to make straight shots because of the restricted lie, loft, and weight. Additionally, the higher offset permits more perfection.

Together, the iron has established itself as a forgiving, comfortable iron that is best used for training by golfers with mid to high handicaps. JPX 921 gives you the flexibility to change your swing and provide more spin to your hits. Low torque allows for straighter, faster hits.

It lacks sufficient forgiveness to allow for simple scoring. Clearly, JPX 921 is a strong performance and improvement iron for golfers who desire to become masters. Okay, that’s all I have for today.
