Special Features
- The PGG4+ replaces both the original floor plate and the internal locking plate as a complete unit, so the extension seats and locks exactly as the factory base pad does with no rattling or movement during use.
- Two additional rounds of 9mm or 40 S&W capacity are added by extending the magazine body downward, using the full internal volume of the extended shell without requiring a longer spring or modified follower.
- The ABS polymer construction keeps weight gain minimal, so the extended magazine handles and drops free from the magwell at the same speed as the factory configuration.
- Compatibility spans the Gen 4 and Gen 5 platform across sub-compact, compact, mid-size, and full-size Glock models in the supported calibers, making the PGG4+ a single part that works across an entire Glock collection.
- Installation requires no tools and no gunsmithing. The floor plate slides off and the PGG4+ snaps into place using the same locking mechanism as the factory base pad.
Practical Benefits
- Concealed carry holders running a Glock 19 or 23 get two additional rounds in every magazine they carry, increasing total capacity without switching to a higher-capacity magazine or changing the profile of the handgun significantly.
- Competition shooters who run Glock pistols in USPSA, IDPA, or similar formats can load more rounds per stage, reducing the number of reloads required and keeping the shooter on target longer.
- Home defense Glock owners who keep loaded magazines ready will find the extra two rounds per magazine a straightforward upgrade that costs less than a single box of ammunition.
- The broad model compatibility means you can equip every magazine across multiple Glock pistols in your collection with a single part number, simplifying ordering and inventory.
- Your Glock magazine performs at the same reliability level you expect from the factory while delivering two more rounds per load, and the Pearce Grip PGG4+ gives you that upgrade with a snap-fit installation that takes under a minute.
The Pearce Grip PG-G4+ Magazine Extension (PGG4+) is a confident choice for any Gen 4 or Gen 5 Glock owner in 9mm or 40 S&W who wants a proven, tool-free capacity upgrade that installs in seconds and functions exactly like the factory floor plate it replaces.
