Testing Glock Barrels: Zero Shift and Accuracy
This video tests the zero shift and accuracy impact of swapping Glock barrels (early Gen 2, late Gen 2, Gen 3, Gen 4, and Faxon match-grade) in a KA Arms Charlie slide equipped with a DeltaPoint Pro red dot. Using a Ransom Rest at 15 yards, the test reveals that while group size remained relatively consistent, barrel swaps did cause a shift in point of impact. Later generation Glock barrels (Gen 3 and Gen 4) and the Faxon match-grade barrel demonstrated improved accuracy and zero consistency compared to earlier generations.
