Loft progression
About the TaylorMade M4
The M4 was TaylorMade's mainstream game-improvement iron for 2018, replacing the 2017 M2. Its new feature was RIBCOR, a pair of internal ribs that run through the heel and toe to stiffen the perimeter and channel more of the impact energy into the middle of the face. A Speed Pocket in the sole, Inverted Cone Technology and a 360-degree undercut cavity carry over from the M-family distance irons. Lofts are strong for the class, with a 28.5-degree 7-iron and a 43.5-degree pitching wedge. Specs below are the men's standard steel-shaft build.

Frequently asked questions
What is the loft of a TaylorMade M4 7-iron?
The TaylorMade M4 7-iron has a loft of 28.5 degrees, with a 63-degree lie and a 37-inch steel-shaft length.
What is RIBCOR in the M4 irons?
RIBCOR is a pair of internal ribs running through the heel and toe of the head. They stiffen the perimeter so that more of the face's flexing happens in the centre, which TaylorMade used to tighten shot dispersion rather than to add outright ball speed.
What is the pitching wedge loft on the M4 irons?
The M4 pitching wedge is 43.5 degrees. The set continues with a 49-degree approach wedge, a 54-degree sand wedge and a 59-degree lob wedge, and starts at a 19-degree 4-iron.
Are the M4 and M6 iron lofts the same?
Almost. Both sets use a 19-degree 4-iron, a 28.5-degree 7-iron and a 43.5-degree pitching wedge. The M6 8-iron is 33 degrees like the M4, but TaylorMade changed the way it measured club length between the two models, so the M6's stated lengths look about half an inch longer.
Finding a used set
The TaylorMade M4 ran from 2018 to 2019 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.
