The MP-18 marked Mizuno's return to a proper muscleback-inspired shape after a stretch of larger, more forgiving MP designs. Within that 2017 family, the players cavity version keeps the compact head and thin topline of a blade but hollows out a small pocket behind the hitting area. You get most of the look and feel of a muscleback with a little more room for error on strikes that miss the center.
These are Grain Flow Forged from 1025E mild carbon steel in Mizuno's Hiroshima factory, which is the same process that built the reputation Mizuno irons still trade on. The 7-iron sits at 34 degrees, which is genuinely traditional. Nothing here is jacked up to fake distance. Loft goes 20 degrees at the 3-iron up to 46 at the pitching wedge, so gapping stays clean and predictable through the set.
This is not an iron that hides your misses. Thin sole, minimal offset, and a small head mean you need to deliver it well. Do that, and the feedback and turf interaction are about as good as forged irons get.
In short
The Mizuno MP-18 (2017) is a players cavity that adds forgiveness without much extra size. The set runs 3-iron to PW with a 34° 7-iron. It carries a $1,099 MSRP.

Carry distances are modeled from TrackMan-based norms scaled to each club's loft, not measured for this exact model.
The cavity is small and sits high behind the sweet spot, so the club looks close to a blade at address while shifting a touch of mass to steady off-center hits. Toplines are thin, offset is minimal, and the sole is on the narrow side, all of which reward a descending strike and punish scooping. The satin finish keeps glare down over the ball. Progressive lofts and a consistent forged construction across the set give you flighted, workable ball flight. The long irons launch a bit easier than a full muscleback would, and the short irons stay compact for control into greens.
The Mizuno MP-18's 7-iron is lofted at 34° - traditional - aligned with classic iron loft standards. For a golfer with an 85-95 mph swing speed, this projects to a 7-iron carry of approximately 136-146 yards. The 5-iron (26°) to 7-iron gap of 8° is spread across a wide range, which may create overlapping distance windows with similarly lofted fairway woods or hybrids. The pitching wedge at 46° is traditionally lofted, pairing naturally with a standard 52° gap wedge.
It is more forgiving than a straight muscleback, but it is still a players iron. If you regularly miss the center of the face, a game-improvement or players-distance iron will hold your ball speed and dispersion better. Steady ball strikers in the low-to-mid single digits are the target here.
The 7-iron is 34 degrees, which is traditional. The set runs from 20 degrees at the 3-iron to 46 at the pitching wedge, so it flights higher and lands softer than the strong-lofted irons that list a lower 7-iron number for more distance.
It is Grain Flow Forged from 1025E mild carbon steel at Mizuno's factory in Hiroshima, Japan. That forging process is the source of the soft, solid feel Mizuno irons are known for.
Same compact footprint and thin topline, but the small cavity moves a bit of weight to the perimeter. Off-center hits hold their line a little better and long irons launch slightly easier, while feel and workability stay close to the blade.
Yes, if you find a set that fits. The forging quality and traditional shape hold up, and used prices are far below current forged players irons. Just get a proper shaft fit, since a small forged head is unforgiving of the wrong shaft.
