Pearce Grip +1 Extension (Glock 43)

The Pearce Grip +1 extension is the essential Glock 43 upgrade. It replaces the factory flush floorplate with a slightly longer molded polymer piece that adds one round of capacity (6 to 7 rounds) and, more importantly, gives the shooter's pinky a place to rest. The stock G43 grip is notoriously short, and most shooters find the pinky either tucks under the magazine floorplate or floats off the gun entirely. The +1 extension fixes this with virtually no increase in concealment footprint.

Installation is tool-less. The factory floorplate slides off, the internal spring and follower transfer directly, and the Pearce floorplate snaps into place. Total install time is under a minute. The extension uses Pearce's OEM-grade polymer and has been the default G43 floorplate upgrade since the pistol launched in 2015.

This is a G43-specific part. The 43X and 48 use longer single-stack magazines with different floorplate geometry; Pearce makes separate +1 and +2 extensions for those platforms. Verify you have the base Glock 43 (6-round factory mag) before ordering.
