The Zero, the off-set and parallax | Learning RED DOTS On Handguns (Part 1)

Published on February 6, 2020
Duration: 9:49

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.

Quick Summary

Sig Sauer Academy recommends a 15-yard zero for handgun red dot sights to minimize holdover/holdunder from 0-25 yards. Parallax effect is minimal at typical distances, and shooters should focus on centering the dot in the optic, not co-witnessing iron sights. Differentiate shooter error from mechanical zero issues for accurate shooting.

Frequently Asked Questions

What is the recommended zero distance for handgun red dot sights?

Sig Sauer Academy recommends a 15-yard zero for handgun red dot sights. This distance is chosen to minimize holdover and holdunder issues for practical shooting distances, typically from 0 to 25 yards, simplifying aiming.

How does parallax affect handgun red dot sights?

Parallax in red dot sights means the apparent position of the dot shifts if the shooter's eye isn't centered. However, for most handgun red dots at typical engagement distances, the effect of parallax on the point of impact is negligible.

Should I focus on co-witnessing iron sights when using a red dot?

When zeroing and shooting with a red dot sight, the primary focus should be on centering the red dot within the optic's window. While co-witnessing can be a backup, the red dot itself is the aiming point, and its position in the glass is what matters most.

What's the difference between mechanical zero issues and shooter error?

Mechanical zero issues relate to the firearm or optic's alignment, while shooter error includes factors like inconsistent trigger press, poor sight picture, or flinching. Analyzing shot groups helps differentiate between these causes of inaccuracy.
