Glock 19 Recoil Spring Assembly Features The Glock Recoil Spring Assembly Dual is built from steel and polymer components engineered to handle the repeated cycling a 9mm Glock pistol experiences over thousands of rounds. Marked 1-7 it is designed specifically for the Glock 19 Gen5 along with the 19X 45 and 47 MOS giving owners of these models a precise factory replacement. Because it is manufactured to the same tolerances as the original part it restores the pistol s slide cycling and recoil management to factory specification. This makes it a dependable fix for a pistol showing signs of a worn recoil spring. The Glock Recoil Spring Assembly Dual addresses the simple fact that recoil springs are a wear item and replacing one periodically helps maintain reliable cycling and felt recoil over the life of a pistol. This assembly ships as a single ready-to-install unit for an experienced owner or gunsmith familiar with Glock disassembly. Keeping a factory spare recoil spring assembly on hand is good practice for duty or competition pistols that see heavy round counts where consistent slide cycling matters most. A genuine Glock recoil spring assembly marked 1-7 is the simplest way to keep a 9mm Gen5 Glock running at its best.
