Glock 17/34 Gen5 Recoil Spring Assembly Dual Features The Glock 17/34 Gen5 Recoil Spring Assembly Dual is a dual recoil spring system built to Glock s own factory specification for Gen5 pistols. Chambered for 9mm Luger it is designed as a direct replacement for the recoil assembly found in a Glock 17 or 34 from the factory. A dual spring design helps manage felt recoil and controls slide velocity through the full cycle of operation. Over time and round count factory springs lose tension and a tired recoil spring can translate into inconsistent cycling and increased wear on other parts. This assembly is built exclusively for the Gen5 platform and is not intended for use in Gen4 or earlier Glock pistols so fitment is specific to that generation. Replacing the recoil spring assembly is one of the simplest and most effective maintenance steps an owner can perform on a Glock. Restoring factory-correct tension helps the slide return to battery consistently and keeps the pistol cycling the way it did when new. The Glock 17/34 Gen5 Recoil Spring Assembly Dual is available for sale at GrabAGun for Gen5 owners maintaining their pistols with genuine Glock parts.
