Lofts compared
- PSi
- M1
What the differences mean
At the 7-iron, the PSi is 31.5° and the M1 is 30.5°, a 1° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the M1 should carry roughly 3 to 4 yards further with that club, on a slightly lower, shallower flight than the PSi. Across the 10 clubs both sets share, the M1 averages 0.8° stronger, with the largest gap at the 5-iron (24.5° vs 23°). The pitching wedges are 45.5° and 45°; the stronger one leaves a 5° jump to a 50° gap wedge, which matters when planning wedge gapping. Beyond loft, the M1 7-iron sits 0.5° flatter (63° vs 62.5°), which nudges start direction slightly right for a right-hander.
The PSi is a players distance iron and the M1 a players iron, so they sit one step apart on the forgiveness scale. The PSi is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly 5 to 15 handicaps who want extra distance from a compact head. The M1 trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits roughly scratch to 10 handicaps.
The PSi is listed as progressive set — cast long irons with a Speed Pocket, forged short irons and the M1 as investment cast multi-material with high-density tungsten. Both use tungsten weighting to lower the centre of gravity and steady the head on off-centre strikes.
The M1 came out 1 year after the PSi, but it is a different line rather than a direct replacement, so the two were designed for different golfers as well as different seasons.
Which should you choose?
The M1 is the stronger-lofted set — up to 1.5° stronger than the PSi on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.

Frequently asked questions
Is the TaylorMade PSi stronger lofted than the M1?
No. The M1 is the stronger-lofted set: its 7-iron is 30.5° against 31.5° for the TaylorMade PSi, 1° stronger and worth roughly 3 to 4 yards of extra carry.
What is the loft difference between the TaylorMade PSi and M1?
At the 7-iron the difference is 1° (31.5° vs 30.5°). The largest gap on a shared club is 1.5° at the 5-iron, and 9 of the 10 shared clubs differ.
Which is better for higher handicap golfers, the TaylorMade PSi or the M1?
The TaylorMade PSi. As a players distance iron it is the more forgiving design, suited to roughly 5 to 15 handicaps who want extra distance from a compact head. The M1 is a players iron, better suited to roughly scratch to 10 handicaps.
Do the TaylorMade PSi and M1 have the same lie and length?
Not exactly. At the 7-iron the TaylorMade PSi is 63° lie and 36.75 inches, the M1 62.5° and 36.75 inches. Both can be bent or built to your own fit.
