This video provides an expert review of the Gen 6 Glock series, comparing factory upgrades against custom builds. Lucas Botkin of T.REX ARMS details significant improvements in slide serrations, optic mounting, frame ergonomics (texture, gas pedal, undercut), and trigger. While the Gen 6 is deemed an objective upgrade, the review suggests dedicated shooters might still prefer custom options for highly specific needs.

Quick Summary

The Gen 6 Glock introduces significant factory upgrades, including aggressive slide serrations, a direct optic mount system (eliminating plates), and improved frame ergonomics with enhanced texture, a gas pedal, and an undercut trigger guard. While offering a snappier recoil due to a shorter spring, it demonstrates strong reliability, even outperforming some custom builds in adverse conditions.

Frequently Asked Questions

What are the main upgrades in the Gen 6 Glock compared to previous generations?

The Gen 6 Glock features enhanced slide serrations, a new direct optic mounting system eliminating plates, and significant frame improvements including aggressive texturing, a gas pedal, and an undercut trigger guard. It also includes a factory flat-faced trigger and a shorter recoil spring assembly.

How does the Gen 6 Glock's recoil compare to older models or custom builds?

The Gen 6 Glock 17 uses a shorter, Glock 19-length recoil spring, which can result in slightly snappier felt recoil compared to the softer-shooting full-length spring found in a Gen 5 Glock 17. Custom builds may vary significantly based on their components.

Is the new optic mounting system on the Gen 6 Glock reliable?

The Gen 6's direct optic mount system, which uses plastic spacers instead of plates for RMR and DeltaPoint footprints, aims to increase reliability by reducing potential failure points associated with removable plates. Testing suggests it performs well.

Are Gen 6 Glocks more reliable than heavily customized Glocks?

In adverse condition testing, such as a 'muddy water' test, factory Gen 6 Glocks demonstrated better reliability than a heavily modified custom Glock, which experienced light primer strikes when dirt was introduced. This highlights potential trade-offs with extensive customization.
