Description
The genuine GLOCK OEM factory recoil spring assembly is a complete, captured drop-in replacement engineered specifically for the Gen4 GLOCK 19 platform. Utilizing GLOCK’s advanced dual-spring design, this assembly spreads the recoil impulse over two distinct stages to significantly smooth out felt recoil, minimize frame battering, and increase muzzle control during rapid-fire strings. Manufactured to identical specs and materials as your pistol’s stock part, it restores 100% factory cycling timing and duty reliability.
