Duration: 17:19

This video delves into the performance benefits of upgrading Glock barrels, contrasting factory designs with aftermarket options like Double Diamond. It highlights how tighter tolerances and traditional rifling in aftermarket barrels improve accuracy and allow for safer use of lead bullets, unlike Glock's hexagonal rifling which can cause fouling. The discussion also touches on slide customization and the ease of barrel installation.

Quick Summary

Aftermarket Glock barrels like Double Diamond offer improved accuracy due to tighter tolerances and traditional lands-and-grooves rifling, which also allows for safe use of lead bullets. This contrasts with Glock's factory hexagonal rifling, designed for reliability in harsh conditions but prone to lead fouling.

Frequently Asked Questions

What is the main difference between Glock factory barrels and aftermarket barrels like Double Diamond?

Glock factory barrels use hexagonal rifling designed for reliability, which can foul with lead bullets. Aftermarket barrels like Double Diamond feature traditional lands-and-grooves rifling and tighter tolerances for improved accuracy and safer use of lead ammunition.

Why do Glock factory barrels have looser tolerances?

Glock factory barrels are designed with looser tolerances, similar to the AK-47 philosophy, to ensure reliable feeding and function even when the firearm is dirty or exposed to harsh conditions, prioritizing reliability over pinpoint precision.

How does barrel hood width affect Glock accuracy?

A wider barrel hood width, like the 0.390" on Double Diamond barrels compared to the factory's 0.387", creates a tighter lockup when the barrel is in battery. This consistency in lockup is crucial for achieving better shot-to-shot accuracy.

Can I safely shoot lead bullets through my Glock with an aftermarket barrel?

Yes, aftermarket barrels with traditional lands-and-grooves rifling, such as the Double Diamond barrels featured, are designed to safely handle lead bullets without the excessive fouling issues that can occur with Glock's factory hexagonal rifling.
