Pearce Frame Insert For Glk Gen4 Sub

The Pearce Frame Insert for Glock Generation 4 Sub is a precision-engineered polymer retention component designed to seal the rear frame cavity on compact and subcompact Glock pistols. This insert is specifically made for Generation 4 models, particularly beneficial for Glock 26, 27, and 33. It provides a solution for those who want to keep their firearms clean and free from debris.

Manufactured by Pearce Grip, a trusted name in firearm accessories, this insert installs via friction fit into the bottom rear cavity of Generation 4 frames. It prevents dust and debris accumulation while maintaining factory backstrap interchangeability. The insert is machined from high-impact polymer, chosen for its durability and resistance to wear patterns that develop during regular use.

This insert is ideal for shooters operating in humid, coastal, or sandy environments, as it seals the rear cavity to extend frame longevity and reduce maintenance. The friction-fit retention method requires no tools, making installation quick and reversible. It is particularly beneficial for those who carry Glock 26, 27, and 33 models as backup guns or for civilian defense.
