What the differences mean
At the 7-iron, the MP-20 HMB is 32° and the MP-20 MB is 34°, 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 HMB should carry roughly 6 to 8 yards further with that club, on a slightly lower, shallower flight than the MP-20 MB. Across the 8 clubs both sets share, the MP-20 MB averages 1.6° weaker, with the largest gap at the 3-iron (19° vs 21°).
The sets are built differently: the MP-20 HMB runs 2-iron to PW (9 clubs), the MP-20 MB 3-iron to PW (8 clubs).
The MP-20 HMB is a players distance iron and the MP-20 MB a blade iron, so they sit 2 steps apart on the forgiveness scale. The MP-20 HMB is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly 5 to 15 handicaps who want extra distance from a compact head. 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 HMB is listed as forged hollow body and the MP-20 MB as forged. The MP-20 HMB'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 MP-20 MB, at some cost in feel. The MP-20 HMB adds tungsten weighting, which lowers the centre of gravity and raises stability on mis-hits, helping the long irons launch.
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 MB is the weaker-lofted set — up to 2° weaker than the MP-20 HMB. That trades raw distance for a steeper landing angle and more predictable stopping power into greens.
