What the differences mean
At the 7-iron, the MP-20 MB is 34° and the MP-20 MMC is 32°, a 2° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the MP-20 MMC should carry roughly 6 to 8 yards further with that club, on a slightly lower, shallower flight than the MP-20 MB. Across the 7 clubs both sets share, the MP-20 MMC averages 1.6° stronger, with the largest gap at the 4-iron (24° vs 22°).
The sets are built differently: the MP-20 MB runs 3-iron to PW (8 clubs), the MP-20 MMC 4-iron to PW (7 clubs).
The MP-20 MB is a blade iron and the MP-20 MMC a players iron, so they sit one step apart on the forgiveness scale. The MP-20 MMC is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly scratch to 10 handicaps. The MP-20 MB trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits low single-digit handicaps who strike the ball consistently.
The MP-20 MB is listed as forged and the MP-20 MMC as forged multi-material. The MP-20 MMC adds tungsten weighting, which lowers the centre of gravity and raises stability on mis-hits, helping the long irons launch. The MP-20 MMC's muscle-back shape keeps mass directly behind the strike for feedback and control, where a cavity spreads it to the perimeter for forgiveness.
Both sets were introduced in 2019, so this is a choice between two models from the same lineup rather than an upgrade: Mizuno designed them to sit side by side for different players.
Which should you choose?
The MP-20 MMC is the stronger-lofted set — up to 2° stronger than the MP-20 MB on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.
