Guns, pistols, rifles are not toys.
They should always be treated as if

Step 1: Clear and Make Safe the
weapon
This is done in 3 easy steps. Please remember to always point
the pistol in a safe direction.
First, release and remove the magazine.
Second, pull back slide to eject a round if one is in the chamber.
Third, visually and physically inspect chamber and barrel to
confirm that the pistol is clear and safe.

Step 2a: Field Stripping Removing the slide
Using a gunsmith hold (Fig 1,2), slowly pull back the slide
~1/8inch (you will hear a slight click, Fig 3).
At this time pull the take down lever (circled in red), and release
the slide (Fig 4).
The slide is now released and will slide off easily (Fig 5).

Step 3: Cleaning the Firearm Using different tools (cleaning rod, cotton swabs, nylon brush)
apply solvent to the firearm.
Make sure to clean dirt from the chamber, barrel, and slide rails.
Also clean out the mag well and the barrel locking tabs on the
frame of the Glock.
You can also use solvent to clean the external of the frame and
slide.

Step 4: Lubing the Glock DO NO lube the inside of the barrel. This is to remain dry.
Only apply one (at most two) drops of oil to the parts that need
lubrication.
Make sure to oil the slide rails and any part of the slide/barrel
that come in contact with each other.

Step 5: Reassemble and dry fire Reinsert barrel into slide. Making sure the block end is towards
the rear of the side.
When inserting the return spring assembly please not the
direction and the resting place of the spring. The end with the
dimple is inserted into the front of the slide and the flat end is
placed it the upper of the two half circle cut outs on the barrel.
Finally slide the slide assembly on to the frame of the pistol and
pull all the way back to cock the firearm
Dry fire the firearm to confirm it goes click.

Troubleshooting
1. Check for an unlocked grip. A Glock must be fired with a
locked wrist. Lock the wrist of your hand when shooting
your Glock.
2. Clean your pistol. Many issues people experience while
shooting are due to dirty and unlubricated guns. Field strip
the Glock and clean all of the internal parts. Oil the gun and
magazine.
3. Inspect the ammunition you are using. Discard any
misshapen or defective rounds. Try a different brand of
ammunition if the ammunition does not look faulty but you
still suspect it to be at fault.
4. Ensure the magazine is fully inserted. Eject and reinsert the
magazine to make sure it is seated all the way inside the
grip of the pistol.
5. Replace any parts that seem to be malfunctioning.
Extractors, recoil springs, and slide stop levers all wear out
with use and may be causing you problems. Visit a
gunsmith and have your gun inspected if you are not sure
which part may be at fault.
6. Contact Glock customer service after you have exhausted
these options. According to Top Glock, "All services
besides general maintenance should be performed by a
Glock Inc. certified armorer."
