Description
The Pearce Grip PG39 Plus Magazine Extension is a drop-in base plate replacement engineered specifically for 9mm Luger subcompact Glock magazines. Molded from high-impact polymer, the PG39 replaces the factory magazine base plate and internal floor plate on third-generation Glock 26, 27, 33, and 39 magazines, adding extra rounds and an additional 1″ of grip length for improved control and comfort.
Capacity gains vary by host magazine: +3 rounds for the Glock 26, +2 rounds for the Glock 27 and 33, and +1 round for the Glock 39. The extended footprint gives a fuller hand purchase without altering the magazine body itself, making the PG39 a popular upgrade for concealed-carry and duty Glock pistol owners who want a few extra rounds on tap.
Finished in black to match factory Glock magazines, the PG39 is a drop-in replacement built from the same durable polymer Pearce Grip uses across its product line for long service life under repeated magazine changes.
