Frequently Asked Questions

What are the main safety concerns with aftermarket Glock triggers like Timney?

The primary safety concerns with aftermarket Glock triggers, such as Timney, include improper installation leading to a lack of trigger safety engagement, accidental discharges due to tolerance stacking when mixing parts, and weak trigger resets that can cause malfunctions. Regular testing is crucial.

How does tolerance stacking affect firearm reliability with aftermarket parts?

Tolerance stacking occurs when slight variations in individual manufactured parts accumulate. When mixing aftermarket triggers, connectors, or housings, these variations can lead to misalignments, fit issues, and functional failures, potentially compromising the firearm's safety and reliability.

What steps should be taken after installing an aftermarket trigger?

After installing an aftermarket trigger, it's essential to perform thorough function checks. This includes verifying the trigger safety tab's operation, testing for accidental discharges, and ensuring the trigger resets reliably. Re-testing after a period of use is also recommended.

Why is it important to avoid mixing aftermarket firearm parts from different brands?

Mixing aftermarket parts from different brands increases the risk of tolerance stacking. Each manufacturer has its own manufacturing tolerances. Combining parts designed with different specifications can lead to poor fit, malfunctions, and compromised safety features, making the firearm unreliable.
