This modular grip system consists of 1 Front Finger Groove (PG-OM1) and 1 Side Panel Grip (PG-OM2). This all-rubber grip provides a more secure and repeatable grip for compact 1911-style firearms. The rubber side panel grip is the same width as the factory grip. The double diamond checkering pattern gives the user a more secure hold as well as maintaining the classic look of the compact GM 1911. The Finger Groove Insert fits under any compact GM 1911 side panel grip adding rubber front finger grooves for comfort and better handling. The side portion of the grip is only 1mm thick, so the overall width is only minimally affected.
