Srixon ZXi4 Irons Review

When I first got my hands on the Srixon ZXi4 irons, I was eager to see how they would perform on the course. Positioned as game-improvement irons, they promise a blend of distance, forgiveness, and feel. After several rounds and practice sessions, here's my comprehensive take on these clubs.

First Impressions and Design

At address, the ZXi4 irons present a clean and confidence-inspiring look. The moderate sole width, extended blade length, and noticeable offset are designed to enhance forgiveness, which is evident when setting up for a shot. The chrome finish combined with a matte face gives them a premium appearance that appeals to both mid and high handicappers. Despite the game-improvement features, they maintain a sleek profile that doesn't feel bulky.

Feel and Sound

One of the standout aspects of the ZXi4 irons is their feel. Srixon has used a softer SUS17-47 steel in the construction, resulting in a noticeably improved feel compared to previous models. Strikes produce a satisfying, muted sound—far from the ‘tinny’ noise you sometimes get with hollow-body irons. The softer feel is particularly noticeable on well-struck shots, giving clear feedback.

Performance on the Course

On the course, the ZXi4 irons deliver exactly what they promise. The hollow-body design, paired with MainFrame face tech (a variable milling pattern on the rear), boosts ball speed and adds forgiveness. Even on off-centre hits, I saw minimal distance drop-off. The Tour V.T. Sole helps the club glide through turf cleanly, which meant fewer fat shots and more consistent contact, especially from uneven lies. The stronger lofts definitely help with distance, but make sure your longer irons don’t bunch up too closely – a gap wedge or hybrid might be needed.

Launch Monitor Data

When tested on a launch monitor, the ZXi4 7-iron (28.5°) gave me high ball speeds and a mid-to-high launch angle, typically around 17–18°. Carry distances were strong, averaging 165–170 yards with a moderate swing speed (around 90mph with a 7-iron). Spin rates sat between 5500–6000 rpm – low enough for extra distance but high enough to stop the ball on the green. The numbers suggest a forgiving iron that still gives you decent control.

Final Thoughts

The Srixon ZXi4 irons sit in that sweet spot between forgiveness and feel. They’ll appeal to players looking to improve consistency without moving into full ‘super game-improvement’ territory. I found them reliable and solid from all types of lies, and their soft feel made them genuinely enjoyable to use.
