What the differences mean
At the 7-iron, the ZX4 Mk II is 28.5° and the ZX7 Mk II is 32°, a 3.5° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the ZX4 Mk II should carry roughly 10 to 14 yards further with that club, on a slightly lower, shallower flight than the ZX7 Mk II. Across the 9 clubs both sets share, the ZX7 Mk II averages 2.3° weaker, with the largest gap at the 7-iron (28.5° vs 32°). The pitching wedges are 43° and 46°; the stronger one leaves a 7° jump to a 50° gap wedge, which matters when planning wedge gapping.
The sets are built differently: the ZX4 Mk II runs 4-iron to SW (9 clubs), the ZX7 Mk II 3-iron to SW (10 clubs).
The ZX4 Mk II is a game improvement iron and the ZX7 Mk II a players iron, so they sit 2 steps apart on the forgiveness scale. The ZX4 Mk II is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly 10 to 25 handicaps. The ZX7 Mk II trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits roughly scratch to 10 handicaps.
The ZX4 Mk II is listed as cast hollow-body multi-material and the ZX7 Mk II as forged. Forging, as in the ZX7 Mk II, is generally credited with a softer feel; casting, as in the ZX4 Mk II, allows more complex cavity and weighting shapes, which is why it dominates forgiving irons. The ZX4 Mk II's hollow body lets the face flex more and moves mass low and outward, usually giving higher launch and more ball speed on off-centre strikes than the ZX7 Mk II, at some cost in feel.
Both sets were introduced in 2023, so this is a choice between two models from the same lineup rather than an upgrade: Srixon designed them to sit side by side for different players.
Which should you choose?
The ZX7 Mk II is the weaker-lofted set — up to 3.5° weaker than the ZX4 Mk II. That trades raw distance for a steeper landing angle and more predictable stopping power into greens.
