The Zero, the off-set and parallax | Learning RED DOTS On Handguns (Part 1)
This guide, based on instruction from Sig Sauer Academy instructor Colin Murphy, details the process of zeroing a red dot sight on a handgun. It emphasizes a 15-yard zero for minimizing holdover/holdunder issues and explains techniques for confirming zero, identifying shooter error versus mechanical issues, and understanding parallax. The instruction highlights that for handgun red dots, the offset is often negligible, and shooters should focus on consistent aiming and trigger control.
