Head To Head: Srixon ZXi7 Versus Mizuno Pro S3

When it comes to player’s irons in 2025, the Srixon ZXi7 stole the show. However, many consumers have been stuck on the idea that Mizuno makes the best player’s irons. We ran both irons through our head-to-head tool to determine how they truly compare when tested side by side. If you are in the market for new player’s irons, you’ll want to see this. You might be in for a surprise.

Distance

• Srixon ZXi7 Distance Score: 9.1
• Mizuno Pro S3 Distance Score: 7.6

Distance is typically not a significant concern for better players seeking solutions for their games.

The ZXi7 is plenty long enough. It ranked seventh for total distance and it delivered impressive carry numbers without compromising control. The launch and spin characteristics helped keep shots in play while still offering solid yardage gains.

The Mizuno Pro S3, by comparison, fell well behind in this category. While some testers appreciated the consistency, others noted it simply didn’t have the firepower of other models in the test.

Forgiveness

• Srixon ZXi7 Forgiveness Score: 9.5
• Mizuno Pro S3 Forgiveness Score: 8.8

This is where the ZXi7 really starts to dominate. Its forgiveness score was the highest in the test, thanks to tight dispersion patterns, low ball speed deltas and minimal distance drop-off on mishits.

The Mizuno Pro S3 was respectable but not elite. It rewards good swings and penalizes bad ones a bit more than Srixon’s model. For players who aren’t consistent with every swing, the Srixon is more likely to keep your ball in play and offer more reliable results.

Accuracy

• Srixon ZXi7 Accuracy Score: 9.5
• Mizuno Pro S3 Accuracy Score: 9.1

Accuracy is always the key category in a player’s iron testing and both clubs performed well. However, once again, Srixon leads. It delivered the best Strokes Gained numbers across all three iron types (PW, 7i, 5i), helping golfers consistently hit tighter shots.

Mizuno’s Pro S3 earned a solid accuracy score and finished in the top 10 overall in this metric. When put up against the ZXi7, it wasn’t quite enough. If you’re prioritizing green-hitting precision, the Srixon is the more complete performer.

Value

Srixon ZXi7 MSRP: $1,299.99
Mizuno Pro S3 MSRP: $1,200.00

Both sets fall into the premium forged iron category. Unless you’re hunting for a discount, pricing likely won’t be the deciding factor between these two.

Final verdict

The Srixon ZXi7 is the top-ranked player’s iron for a reason. It combines elite accuracy with top-tier forgiveness and better-than-expected distance. It’s the complete package.

The Mizuno Pro S3 still holds its own, especially for those who value feel and precision. It looks and sounds great and better players will appreciate the traditional shaping. However, from a performance standpoint, Srixon is tough to beat.
