About the Mizuno MP-20 HMB

The MP-20 HMB is a hollow-body iron sold as a full 2-iron through pitching wedge set rather than as a long-iron replacement only. A Grain Flow Forged Chromoly face and neck section is fused to a multi-material body, with high-density tungsten placed in both the toe and the heel. It shares the loft and lie progression of the MP-20 MMC, with a 32-degree 7-iron and a 46-degree pitching wedge, but carries slightly more offset at 0.126 inches in the 7-iron and less bounce in the long irons, which are listed at 0 degrees in the 2- and 3-iron. All figures are the men's standard steel-shaft specification.

Finding a used set

The Mizuno MP-20 HMB is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
