Frequently Asked Questions

How can I fix 'brass to face' ejection issues on my Gen 3 Glock?

A common fix involves replacing the stock ejector with a Gen 5 ejector (part number 47021). Installing this into the Gen 3 trigger housing often resolves erratic ejection, especially when running an optic, by improving the direction and consistency of spent casing expulsion.

What is the Holosun SCS and why is it relevant for Glock MOS?

The Holosun SCS is a Solar Charging Sight designed for direct mounting onto Glock MOS (Modular Optic System) slides without needing adapter plates. Its low profile allows co-witnessing with standard iron sights, making it a practical choice for concealed carry optics.

Can aftermarket triggers cause reliability problems in Glocks?

Yes, aftermarket triggers can sometimes introduce reliability issues if not properly installed or if compatibility is not fully understood. The video highlights an instance where an Apex Tactical kit caused total trigger failure in a Shadow Systems MR920, emphasizing the need for thorough testing.

What is the purpose of the Gen 5 ejector swap on a Gen 3 Glock?

The Gen 5 ejector swap (using part 47021) is performed to correct inconsistent ejection patterns in Gen 3 Glocks. This modification helps ensure spent casings are thrown clear of the firearm's action and any mounted optic, preventing malfunctions like stovepipes.
