Glock 17/34/22/35/37/31 gen 3 recoil spring
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.
A single spring demonstrates linear damping. Constructed of stainless steel with a chrome silicon spring. Cold drawn and heat treated before fabrication.
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.
