Pearce Grip PGG4PLUS Magazine Extension for Glock Gen 4 and Gen 5, 9mm, .40 S&W, .357 SIG, and .45 GAP

The Pearce Grip PGG4PLUS Magazine Extension adds capacity to select Generation 4 and Generation 5 Glock sub-compact, compact, mid-size, and full-size magazines. Designed as a direct replacement for the original magazine floor plate and internal locking plate, this black magazine extension provides additional room while maintaining a clean, factory-style appearance. It is a practical upgrade for range use, training, and applications where increased magazine capacity is desired.
The PGG4PLUS adds two rounds to compatible 9mm magazines, two rounds to .40 S&W and .357 SIG magazines, and one round to .45 GAP magazines. Its purpose-built design helps extend magazine capacity without requiring a complete magazine replacement. The extension is manufactured by Pearce Grip and is identified by part number PGG4PLUS, making it easy to match with compatible Glock magazine configurations.
Compatibility is limited to Generation 4 and Generation 5 Glock magazines in supported sub-compact, compact, mid-size, and full-size models. This extension does not fit Glock 10mm or .45 ACP magazines. Verify your Glock generation, caliber, and magazine configuration before installation. Professional installation or function testing is recommended to confirm reliable feeding and proper magazine operation after installation.
