The GRGM21M is an RG-style short-scale solid body electric guitar model introduced by Ibanez in mid-2009. It is produced in China as part of the entry-level GIO line.

The GRGM21M features a basswood (later poplar) body bolted to a 22" (560mm) scale maple neck with a 24-fret maple fingerboard with dot position markers. Components include dual Ibanez Powersound humbucking pickups and a standard hard-tail bridge.

For 2017 the Powersound pickups were replaced with Ibanez Infinity R humbuckers. For 2018 the bridge was specified as the F106. For 2019 the body species was once again basswood and the 3-way lever pickup selector was replaced with a 5-way.

The GRGM21M was offered as part of the IJM21M Jumpstart package also containing a practice amp and various accessories sold in the US. The "Black night" (BKN) color was available only as part of this package. The GRGM21M is also sold with a gig bag with a package model number of GRGM21MGB.
