WL™ on Glock 17, 18 or 19

GSC™ is a light-weight device (12 gr) – having no noticeable effect on the operation of the gun. It is invisible – installed in the socket behind the magazine well.

Installing WL™ in a Glock 17, Glock 18 or Glock 19

Hold the GSC™ with the flat side facing forward and insert it into its slot behind the magazine. Apply enough pressure to insure the GSC™ is securely seated flush in the slot behind the magazine well.

Push the GSC™, using force until the pin extends out of the socket.
When properly installed, it will look like this

The GSC™ must fit tightly within its slot. If the GS-Counter does not fit tightly, or if the GS-Counter slides too easily into place without the application of force, attach stickers to act as shims to the flat side of the GS-Counter to eliminate any play or free-movement.
For Glock 17, if the GS-Counter does not fit tightly, or if the GS-Counter slides too easily into place without the application of force, attach stickers (found in the package) to act as shims to the flat side of the GSC™, to eliminate any play or free-movement.

Removing the WL™ before Cleaning the Gun

Push the pin with a small object (a pen for example) and pull out the WL™ unit.
Once you have finished cleaning the gun, re-install the WL™, as described in How to Install the WL™ section.
