The Glock Recoil Spring Assembly for Gen3 Glocks. This Glock Recoil Spring Assembly Gen3 comprises of a single spring element. This element is assembled together with a central guide rod. When should I change my Glock recoil spring? How long does a Glock recoil spring last? Please read on for that information.
How long does a recoil spring assembly last?
A single spring element demonstrates linear damping. The Glock Gen 1 to Gen3 recoil spring is constructed of stainless steel with a chrome silicon spring. Furthermore it is cold drawn and heat treated before fabrication. This spring should last 5000 cycles before replacing is required.
When Should I change my Glock recoil spring?
Glock Engineers recommend spring replacement after 5000 cycles. This is as result of the spring getting weaker after many cycles. A fatigued spring does not decelerate the slide sufficiently. The shock load of the slide coming to a rapid high G-force stop will eventually start to break internal parts such as the pins, the locking block and even portions of the frame itself.
