Frequently Asked Questions

What are common Glock reliability issues and how can they be avoided?

Common Glock reliability issues stem from aftermarket parts altering critical timing, and problems with magazines. To avoid them, stick to OEM parts where possible, especially for magazines, and be cautious with trigger modifications that can reduce striker energy or alter engagement surfaces.

How do Glock generations differ, and why does it matter for owners?

Glock generations (Gen 3, 4, 5) feature distinct differences in recoil spring assemblies, magazine releases, frame textures, and slide stop designs. These variations impact part compatibility, feel, and what to inspect before trusting the firearm, making it crucial for owners to know their generation.

What is the purpose of the Glock Safe Action trigger system?

The Glock Safe Action trigger system is designed as a duty trigger, not a competition one. It performs multiple safety functions simultaneously, featuring a long take-up and a defined wall for consistency. The factory pull weight is typically set around 5.5 pounds.

Why is it important to keep the Glock striker channel dry?

The Glock striker channel is designed to function without lubrication. Applying oil attracts grit and debris, which can slow down the striker's movement or cause it to fail to reset properly, leading to malfunctions. It's best to clean it with solvent and keep it dry.
