Glock 43 Breakdown Pt. 3 - Lower Disassembly

Published on June 26, 2015
Duration: 19:34

This video provides a detailed, step-by-step guide to disassembling and reassembling the lower receiver of a Glock 43. It highlights unique aspects of the G43's lower compared to older Glock models, particularly the slide lock lever mechanism and trigger pin removal. The instructor emphasizes specific techniques and tools needed to overcome common difficulties, such as the spring-loaded slide lock lever's interference with the trigger pin.

Quick Summary

The Glock 43's trigger pin removal is complicated by the slide stop lever's spring-loaded mechanism, which can lock onto the pin. To overcome this, the slide stop lever must be actively depressed to release the tension before the trigger pin can be extracted. This often requires a helper or specific techniques to manage the spring pressure.

Frequently Asked Questions

What makes removing the trigger pin on a Glock 43 difficult?

The trigger pin removal on a Glock 43 is challenging because the slide stop lever, with its unique spring mechanism, interferes with the pin. The lever's notch can lock onto the trigger pin due to spring pressure, requiring the lever to be depressed to release this tension before the pin can be removed.

How does the Glock 43's trigger spring system differ from older Glocks?

Unlike older Glock models that use a leaf spring, the Glock 43 features an internal coil spring system within the trigger housing. This spring has a guide rod and a metal piece with a hook that interacts with the trigger bar to provide the trigger return function.

What is the benefit of using a machined slide lock lever on a Glock 43?

A machined slide lock lever, compared to a factory stamped one, is often flatter and more precisely manufactured. This improved flatness can lead to more consistent firearm lockup, potentially enhancing accuracy and reliability. It can also be slightly easier to manipulate due to extended features.

Can I improve the trigger pull on a Glock 43?

Yes, you can improve the trigger pull on a Glock 43 by installing an aftermarket 3.5 lb connector. This modification can significantly reduce the trigger pull weight, making it lighter and potentially increasing accuracy without compromising the firearm's safety features.
