Lofts compared
- RSi 1
- M2
What the differences mean
At the 7-iron, the RSi 1 is 30.5° and the M2 is 28.5°, a 2° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the M2 should carry roughly 6 to 8 yards further with that club, on a slightly lower, shallower flight than the RSi 1. Across the 10 clubs both sets share, the M2 averages 1° stronger, with the largest gap at the 7-iron (30.5° vs 28.5°). The pitching wedges are 44° and 43.5°; the stronger one leaves a 6.5° jump to a 50° gap wedge, which matters when planning wedge gapping.
The sets are built differently: the RSi 1 runs 3-iron to LW (11 clubs), the M2 4-iron to LW (10 clubs).
Both are game improvement irons, built for roughly 10 to 25 handicaps. Perimeter-weighted cavity backs with wider soles, more offset and stronger lofts, aimed at mid handicaps. Because they target the same golfer, the decision comes down to the specific loft, feel and shaping differences rather than who the sets are made for.
The RSi 1 is listed as investment cast and the M2 as investment cast with Speed Pocket sole slot. With the build method this similar, differences in feel come down to head size, sole width, topline and offset rather than how the heads are made.
The M2 arrived 2 years after the RSi 1, a typical one-generation refresh. Changes over that span are usually incremental: refined face thickness, revised weighting, updated looks and small loft tweaks rather than a new concept. Here the 7-iron loft moved from 30.5° to 28.5°.
Which should you choose?
The M2 is the stronger-lofted set — up to 2° stronger than the RSi 1 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 RSi 1 stronger lofted than the M2?
No. The M2 is the stronger-lofted set: its 7-iron is 28.5° against 30.5° for the TaylorMade RSi 1, 2° stronger and worth roughly 6 to 8 yards of extra carry.
What is the loft difference between the TaylorMade RSi 1 and M2?
At the 7-iron the difference is 2° (30.5° vs 28.5°). The largest gap on a shared club is 2° at the 7-iron, and 8 of the 10 shared clubs differ.
Are the TaylorMade RSi 1 and M2 aimed at the same golfer?
Yes. Both are game improvement irons, built for roughly 10 to 25 handicaps. Choose on feel, looks and gapping, ideally after hitting both.
Do the TaylorMade RSi 1 and M2 have the same lie and length?
At the 7-iron, yes: both are 63° lie and 37 inches long.
