Pearce Frame Insert For Glk G4 Full

The Pearce Frame Insert for Glock G4 Full is a high-impact polymer accessory designed to seal the bottom rear cavity of Generation 4 and 5 Glock frames. This frame insert uses the factory lanyard hole for secure retention and prevents dust, debris, and moisture from entering the frame cavity—a practical concern for shooters who train in variable environments or operate near salt water and harsh conditions.

Installation is straightforward: the insert fits into the existing cavity without modification to the frame or removal of internal components. The high-impact polymer construction resists UV degradation and maintains structural integrity across temperature and humidity extremes. Critically, the design preserves compatibility with Glock's factory interchangeable backstraps, so users can continue to customize grip texture and size without removing the insert. At just 0.06 lbs and measuring 2.75 x 1.4 x 4.1 inches, the insert adds negligible weight while providing a complete seal against contamination.

This accessory addresses a real gap for duty and training shooters who operate in wet, sandy, or dusty environments. The frame cavity cavity is designed to house the lanyard attachment point and empty space—without a protective insert, this becomes a collection point for contaminants that can affect trigger function over time. The Pearce insert is equally relevant for competition shooters prioritizing frame cleanliness and for armed professionals who demand reliable, low-maintenance equipment. Fits Glock models M17, 18, 19, 22, 23, 24, 31, 32, 34, 35, 37, 38, and 45 in Generation 4 and 5 configurations.
