Pearce Grip PGFI21G4 Grip Frame Insert for Glock 20/21/41 Gen4 - Black Polymer$3.29
Availability: In Stock
The Pearce Grip PGG4MF polymer grip frame insert is a simple, practical upgrade for Glock Gen4 and Gen5 mid-size and full-size pistols. This small but effective accessory fills the hollow cavity at the bottom rear of your Glock's frame—a gap that's purely aesthetic on stock guns but can collect dirt, lint, and debris during carry or storage. By sealing that opening, the insert keeps your pistol cleaner inside and gives the grip a finished, professional appearance.
Installation is straightforward: the insert snaps into place using the lanyard hole for retention, requiring no tools or permanent modifications. The front lip is engineered to seat flush against the mag well, ensuring smooth magazine seating every time. It's compatible with Gen4 and Gen5 Glock 17, 18, 19, 22, 23, 24, 25, 31, 32, 34, 35, 37, and 38 models in mid-size and full-size configurations. The insert works alongside factory interchangeable backstraps on Gen4 frames, so you don't lose any customization options. Keep in mind this insert does not increase magazine capacity and is not compatible with Glock 20, 21, 40, or 41 models.
Whether you carry daily, hit the range on weekends, or just want to keep your Glock looking sharp and running clean, this is a no-nonsense addition that costs almost nothing but delivers genuine utility. It's the kind of small detail that separates a well-maintained defensive or duty gun from one that's been neglected.
