What the differences mean
Every club the two sets share has exactly the same loft, starting with a 35° 7-iron. On paper there is no distance or trajectory difference: with the same swing, a 7-iron from either set should launch and carry about the same. The real differences are in how the heads are built, how they look at address and how they feel at impact, none of which a spec table can show.
The sets are built differently: the CG1 runs 1-iron to PW (10 clubs), the 588 Forged MB 3-iron to PW (8 clubs).
Both are blade irons, built for low single-digit handicaps who strike the ball consistently. Compact muscleback irons with minimal offset, thin toplines and the smallest sweet spot — built for shot-shaping over forgiveness. 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 CG1 is listed as Carbon Metal Matrix (CMM) muscle back and the 588 Forged MB as forged muscle back. 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.
There are 9 years between these sets (2004 and 2013), more than one design generation. Over that time irons moved toward stronger lofts, thinner and faster faces, hollow and multi-material heads and wider use of tungsten, so the newer set is not simply a better version of the older one: it may launch and spin quite differently.
Which should you choose?
The CG1 and 588 Forged MB share the same lofts on every club on file, so the difference is in head construction, feel and forgiveness rather than trajectory.
