About the Titleist ZM
The Z•M Forged ("Z Muscle") is the traditional muscleback of the four irons Titleist announced in January 2008 alongside the AP1, AP2 and ZB, at retail from 15 March 2008. Titleist's spec page lists it as forged 1020 mild carbon steel, with a compact head, constant blade length and a narrow sole with mild bounce, the Z back design placing the center of gravity in the middle of the face. Lofts moved one degree stronger than the 695.MB from the 6-iron down, to a 35 degree 7-iron and 47 degree pitching wedge, and the 710 MB that replaced it in 2009 kept the ZM specs unchanged. The stock set ran 3-iron through pitching wedge.

Frequently asked questions
What is the loft of a Titleist ZM 7-iron?
The Titleist ZM 7-iron is 35 degrees, with a 63 degree lie and a 37 inch standard steel length.
How do the ZM lofts compare with the 695.MB it replaced?
The long irons match, but the ZM is one degree stronger from the 6-iron down: a 35 degree 7-iron against 36 and a 47 degree pitching wedge against 48. The 710 MB then kept the ZM lofts unchanged.
What is the difference between the Titleist ZM and ZB irons?
The ZM is a muscleback throughout with minimal offset and a narrow sole, while the ZB blends cavity back long irons into muscle back short irons with slightly more offset and a wider sole in the 2-7 irons.
Finding a used set
The Titleist ZM ran from 2008 to 2009 and is no longer in production, so the used market is the only source. Search the used listings on eBay, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
