Glock Lower Receiver Disassembly

Glock lower receiver disassembly can be done easily if you pay close attention to where the springs attach. The tools you will need are pair of needle-nose pliers, a one sixteenth inch punch and an eighth inch punch, in addition to a small screwdriver or, as I'm using, a solder cleaning tool.


First make sure that the magazine is removed and there is not a round in the chamber. Next we will remove the three pins. Two above the trigger guard and one at the top back of the hand grip. Always push or remove pins from a firearm from left, out the right side. When you reinsert pins in a firearm, reinsert from right to left. The reason this is done is as to not enlarge the hole on the left side of the firearm. This is the accepted procedure gunsmith came up with long ago. The block pin will be the first one we will remove.

Usually the pins in a Glock can be removed by holding the receiver in your hand and pushing the pin out with a punch making Glock lower receiver disassembly easy. Remember to push them out the right side of the receiver. Next we will remove the PIN at the top of the hand grip, then remove the larger pin right above the trigger.


Glock Lower Receiver Disassembly

This larger pin is sometimes difficult to remove. If you have trouble removing this pin, do not use a hammer! Simply move the slide release up and down, forward and backward, as you're working the pin out. This pen is retained by the slide release spring.

After you remove these pens, you can lift out the slide release, block and the trigger mechanism.

After you have removed these items, you will remove the magazine release.

Using a small light in the bottom of the magazine well, you'll see a long wire spring going from the bottom of the V inside of the front of the hand grip, to the magazine release lever. Using a small screwdriver, or in my case, a solder cleaning tool, work the pen over and out of the slot in the mag release.

While holding the magazine release in place, use a pair of needle-nose pliers to pull the wire spring straight up and out of the magazine well. Once you have removed the spring you can push the magazine release out of the hand grip.

The next item to disassemble is the trigger mechanism. This mechanism is disassembled by turning the trigger bar diagonally and then lifting it from it's slot. Pay close attention to how the spring is attached at the back of the trigger bar linkage. The spring comes in from the bottom and back then goes in through the hole. On the other end, the spring comes over the top and back out the back. Notice the S configuration the spring is attached in. Reassemble in the same fashion.

We will remove the take-down lever from the lower next. It's retained by flat spring.

Pressing the flat spring down with a small punch, you can slide the take down lever out from the left to the right just like you did the pins. Push it partially out through one side with your small screwdriver and then pull it all the way out. There is a notch in the bottom of the take down lever where the spring fits in, holding it in place. Notice how the take down lever is positioned with the tall, grooved section turned up and towards the back.

The flat spring should then be removed. Be careful removing the spring and do not bend it. Pay close attention to which part of the spring goes down into the frame and which end holds the take down leaver in place. You can work it out with a small screwdriver or needle nosed pliers, being careful to not bend it.

This accomplishes Glock lower receiver disassembly.

Reassembly Is The Reverse of Disassembly

Reinsert the flat spring back into his hole, paying attention to which end goes down. Once returned to it's proper location, use a small screwdriver to send it all the way home. Next we will return the take-down lever to it's place, paying attention to which end goes up. While holding the spring down with a small punch or screw driver, push it partially over the spring. Release the spring and push the take down leaver the rest of the way in. You will hear and feel the flat spring lock in.

Next, return the trigger mechanism back into the receiver. First insert the trigger down into the trigger guard and then set the rear part of the trigger mechanism into the hand grip. Take the lock block and return it to its location. Then return the slide release to its position.

The first pin replaced will be the larger pin. Remember to insert pins in a firearm from the right side towards the left side.

Look through the larger hole and move the slide release around until it's centered. Notice on the larger pen there are two machined areas around it's circumference at each end. It makes no difference which end you put in first. Once you press the pin in, you will feel it click into place on the spring from the slide release.

The next pen is the block pin. Start it in and press it all the way through.

The last pin is the one at the top of the hand grip.

Once all three pins are in place, center them up with your punch.

After you have returned and centered the pens, return the magazine release to it's location. Generation 4 Glocks have an ambidextrous magazine release feature. The magazine release can be changed for either a left-handed or right-handed shooter.

Return the wire spring for the magazine release back into its proper position. Using a small flashlight in the bottom of the magazine well and a pair of needle-nose pliers, return this wire spring into its proper hole. There is a "V" in the magazine well of which at the bottom is a hole for the spring. Return the spring to that whole, ensuring that it goes all the way to the bottom. Using a small screwdriver or some other small tool, return the spring to its slot in the magazine release. Make sure that is in the proper position.

Once all of this has been done, you can return the slide back to the lower polymer of the Glock handgun.

Check the handgun for proper operation of the trigger mechanism and slide.

Now you know how to preform Glock lower receiver disassembly and reassembly.
