Testing Glock Barrels: Zero Shift and Accuracy
This video performs a detailed comparison of Glock 19 barrels, focusing on the impact of changing barrels on the zero of a red dot sight. The creator utilizes a Ransom Rest to eliminate shooter error, firing identical groups with various generation Glock OEM barrels and a new Faxon "match grade" Glock 19 barrel. The primary questions addressed are how much zero shift occurs when swapping barrels and which barrels yield the tightest groups, highlighting the practical accuracy advantages of red dot equipped pistols.
