Frequently Asked Questions

What are the essential safety steps before disassembling a Glock 43?

Before disassembling a Glock 43, always ensure it's unloaded. Drop the magazine, pull the slide back, and visually inspect the chamber. Then, pull the trigger in a safe direction. Keep all ammunition and loaded magazines completely separate from your workspace.

How do you remove the slide from a Glock 43?

To remove the slide from a Glock 43, pull the slide back about a quarter inch, pull down the slide lock lever, hold it down, release the slide, and push it forward off the receiver. Ensure you hold the slide securely during this process.

What is the correct procedure for removing the striker from a Glock 43 slide?

To remove the striker, first turn the slide upside down. Lift the striker slightly, then push down on the spacer sleeve underneath it to release spring pressure on the slide cover plate. Carefully thumb off the slide cover plate, then pull the striker assembly straight out.

Why should you avoid oiling the striker channel in a Glock?

Oiling the striker or firing pin channel in a Glock is not recommended. Excessive oil can create hydraulic pressure, interfere with the striker's movement, and attract dirt, grime, and debris, potentially causing malfunctions.

What is a common mistake made during Glock 43 reassembly, and how can it be avoided?

A common mistake is losing the small striker spring cups. During reassembly, a trick is to lock the striker's lug onto the back of the slide to keep it from compressing, allowing easier installation of the spring cups and spring.
