Pearce Grip Frame Insert for GLOCK (Gen 4) 20/21/40/41

The Pearce Grip Frame Insert for GLOCK (Gen 4) 20/21/40/41 is a precision-engineered accessory designed for serious shooters and tactical operators who demand reliability in harsh environments. Whether you're running drills at the range, deployed in field conditions, or maintaining a duty weapon, this frame insert addresses a critical vulnerability: the lanyard hole cavity at the base of your GLOCK frame. Without protection, this hollow void collects dust, sand, saltwater spray, and debris—exactly the contamination that compromises function. This insert seals that gap while maintaining the clean aesthetic of your firearm.

Manufactured from high-impact polymer, the Pearce Grip Frame Insert utilizes the existing lanyard hole for secure retention, requiring no gunsmithing or permanent modification. The material resists impact, UV exposure, and chemical degradation—critical properties in salt-air and freshwater environments where corrosion and material failure are constant threats. At just 0.03 lbs, it adds no appreciable weight or bulk, and its compact 2.7 x 1.35 x 3.55-inch profile integrates seamlessly into the GLOCK's ergonomics. Installation is tool-free and takes seconds, making it equally suitable for duty carry, training, or storage protection.

Shooters operating the GLOCK 20, 21, 40, or 41 in Generation 4 configuration—particularly those in marine, coastal, or high-debris environments—benefit most from this protective insert. Law enforcement, military personnel, competitive shooters, and firearm owners who store weapons long-term all recognize the value of dust and debris exclusion. The insert is not compatible with earlier GLOCK generations, so confirm your Gen 4 frame before purchase. Its low cost and zero maintenance make it an essential addition to any serious operator's inventory, delivering tangible protection against environmental degradation with zero operational compromise.
