What Is A Glock Slide Lock Spring?

The slide lock spring is a "L" shaped piece of spring steel that is installed into the frame or receiver of a Glock pistol. When installed, this spring mates with the slot in the slide lock and pushes it upwards against the frame. The spring also keeps the slide lock aligned within the frame.

How Does A Glock Slide Lock Spring Work?

The Glock slide lock is simply a bar that runs across the frame from side to side. There is a little piece of spring metal (the spring) that runs underneath it which keeps upward pressure on the slide lock. There is a groove in the slide lock into which the spring locks into. The bar lock keeps the slide on the frame. It allows the slide to ride back and forth for recoil but does not allow the slide to ride forward and off the frame. When you pull down on the slide lock all you are doing is clearing the path for the slide to ride off the frame.

The spring pushes the slide lock into it's "Up Position". When the tabs are pulled down, the spring is depressed and the side lock is lowered within the frame.

How Do You Remove And Replace The Glock Slide Lock Spring?

Once the slide lock is removed, the removal and replacement of the spring is easy. It just pry's out. Here are the instruction on how to do it.

GLOCK SLIDE LOCK SPRING REMOVAL

REMOVE THE GLOCK SLIDE LOCK
Remove the slide lock per procedure Glock Slide Lock Replacement Instructions. It looks like a little flat bar with knurled edges, but it performs an important function. It keeps the slide from coming off of the frame and acts as a release mechanism for field stripping the pistol.
IDENTIFY THE SPRING
The spring is that thin strip of spring steel inside the frame. If you push down on the end nearest the slide lock you can feel the tension of the spring as it moves slightly.
SEE THE SPRING FROM THE SIDE SLOT
Look at the spring from one of the side slots in the frame. You can see it in the picture high in the slot. When you reinstall the slide lock you will have to push down on the spring to get it beneath the slide lock.
DISLODGE THE SPRING
Using a thin punch or small screw driver push the spring upward from one of the side slots. This will help to dislodge it from it's installed position.
REMOVE THE SPRING
Then with a flat head screw driver, from the top of the frame gently get under the spring and pry it out of it's hole/slot.

Note: The above procedure illustrates the removal and installation procedure for a Glock 19 pistol. The procedure is the same for all Glock pistols. Normally you would never have to remove and replace the spring. It should last the lifetime of the pistol. The only reason I took out the spring was to see how it worked and to clean it.
