Loft and head design separate these two. The Mizuno Pro M-15 runs its 7-iron at 30.5 degrees, 3 degrees stronger than the Pro M-13 at 33.5 degrees, which works out to roughly 7 yards more carry at the same swing speed. It is also the only one of the pair tagged with tungsten weighting. The Mizuno Pro M-13 is a players cavity back whose stock set starts at the 3-iron, and it holds ratings of 78/100 from Golf Digest and 86/100 from MyGolfSpy. The M-15 has no editorial recognition on file. Both are forged with progressive lofts, and both list at $1299, so price does not separate them. The M-15 suits a golfer chasing distance. The M-13 suits a better ball striker who wants a traditional cavity back and a long iron in the set.
At the same price, the Pro M-13 is the safer pick for most golfers. It has two published ratings behind it and a fuller stock set. Choose the Pro M-15 only if distance is your priority and you are willing to check your wedge gapping, since the stronger 7-iron pushes the whole set longer. If feel and a classic cavity back matter more than yards, the M-13 is the one to buy.
