This review from T.REX ARMS analyzes the new Generation 6 Glock pistols, comparing factory upgrades against custom builds. The Gen 6 features significant improvements in slide serrations, optic mounting, frame texture, and controls. While an objective upgrade over previous stock generations, the video suggests dedicated shooters may still prefer custom options for highly specific needs. The analysis includes shooting comparisons, reliability tests in adverse conditions, and an assessment of trigger and grip performance.

Quick Summary

The Gen 6 Glock introduces significant factory upgrades including aggressive slide serrations, a direct optic mount system, enhanced frame texture, a 'gas pedal' thumb rest, and extended controls. While an objective improvement over stock Glocks, its shorter recoil spring results in slightly snappier recoil. Reliability in adverse conditions often surpasses heavily modified custom builds.
