Hello all, Does anyone know at what range the Glock handguns are zeroed at the factory? (The search function is not working for me, something about the token has expired. I don't know what that means). It is 25yds/meters or 50yds/meters? I have tried searching the net with no luck, read the manuals for glock and browning and no mention at what range the pistols are zeroed at. Thanks for your time in advance.
