The rest of the barrels tested in this video were different generation Glock OEM.
I recently acquired a brand new Faxon "match grade" Glock 19 barrel, and in the process of swapping it out, I was curious: how much of a zero shift would I see now that I have a red dot enhanced pistol?
The practical accuracy capabilities of a red dot enhanced pistol are much improved over standard sights.
How much does zero shift if you change barrels?
Which barrel(s) provide the best groups?
To perform this test, I used a ransom rest and did not move the frame throughout the process, swapped out barrels, and fired 5 round groups out of each barrel without changing the point of aim.
