Srixon ZX irons are a line of forged irons that sit between a blade and a game improvement iron, with the ZX7 for better ball strikers, the ZX5 in the middle, and the ZX4 for players who want more forgiveness. The updated ZX Mk II versions launched in the U.S. in January 2023, and they are a good used buy because Srixon's forged irons hold their feel for years.
What is the Tour V.T. Sole?
The Tour V.T. Sole is a V shaped sole with notches that Srixon says reduces drag and helps the club keep speed through impact. In plain terms, the leading edge and trailing edge are shaped so the club cuts through turf instead of digging. It is most noticeable on softer ground and on slightly heavy strikes, where the club tends to keep moving instead of stopping.
How do the ZX7, ZX5 and ZX4 Mk II differ?
All three ZX Mk II models use forged 1020 carbon steel. The ZX7 Mk II adds a feature Srixon calls PureFrame, which puts a thicker section of steel behind the sweet spot for feel, and it is aimed at the best ball strikers. The ZX5 Mk II and ZX4 Mk II use MainFrame, a pattern of channels and variable grooves designed to help the face flex. All three use progressive grooves, wider on the 3 to 7 irons and deeper on the 8 iron through the gap wedge. Combo sets that mix two models are common, and a lot of players carry ZX5 in the long irons and ZX7 in the short irons.
Common questions
Are Srixon ZX irons forgiving?
The ZX4 is the most forgiving of the three and the ZX7 is the least. If you hit the center of the face most of the time, any of them is playable. If you miss a lot, start with the ZX4 or ZX5.
What is the difference between ZX and ZXi?
ZXi is the newer generation that came after the ZX Mk II. We stock both, and the ZX Mk II is usually the lower priced option on the used market.
