Glock OEM 17T Simulation & Training Recoil Spring Assembly

Glock 17T Recoil Spring

This is the factory recoil spring assembly for the Glock 17T, the training variant built to fire Simunition and other non-lethal marking rounds. The recoil spring assembly sits under the barrel and controls how the slide cycles each shot, so a worn or wrong spring means failures to feed and eject. If you run a 17T for force-on-force training and need to replace a tired unit, this is the correct Glock OEM part rather than an aftermarket substitute.

Features

• Glock OEM Part — Made by Glock to the factory specification for the 17T, so it drops in without fitting or tuning.
• Captured Assembly — The spring is held on its guide rod as one unit, which keeps installation simple and avoids losing a loose spring during takedown.
• Steel Construction — The coil spring is wound from steel for the cycle life a duty or training pistol needs.
• Dual Recoil Spring — Two nested springs on the guide rod, the Glock arrangement that smooths slide travel and helps the pistol cycle reliably.
• 17T Simunition Tuning — Calibrated for the 9mm FX marking rounds the 17T is built to fire, which cycle differently from standard duty ammunition.
• Polymer Guide Rod — Built on the standard Glock polymer rod rather than a metal replacement, matching the original 17T configuration.
• Direct Replacement — Swaps in for the original 17T recoil spring assembly during routine maintenance or after the spring fatigues.
• Full-Size Length — Sized for the full-size Generation frame the 17T uses, not the compact or subcompact models.

Fit And Service

The recoil spring is a wear part. It loses tension over a service life and should be replaced on a schedule, especially on a training pistol that sees heavy round counts. This assembly is specific to the Glock 17T and its marking-round system; it is not interchangeable with the standard Glock 17 duty spring. Confirm your model before ordering so the spring weight matches what your pistol was built to run.
