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

Published on February 6, 2020
Duration: 9:49

This guide, presented by 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 improved accuracy within 25 yards, proper setup using a rest, and the importance of focusing on the dot's position within the optic rather than iron sight co-witnessing. The video also addresses handgun red dot offset and parallax, concluding they are negligible at typical engagement distances.

Quick Summary

Sig Sauer Academy recommends a 15-yard zero for handgun red dot sights to minimize holdover and holdunder issues from 0 to 25 yards. Parallax and mechanical offset are considered negligible at typical handgun engagement distances, meaning shooters should aim directly at their point of impact.

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 common engagement distances ranging from 0 to 25 yards, providing a more practical aiming solution.

How does parallax affect handgun red dot accuracy?

Parallax has a negligible effect on point of impact for handgun red dot sights at typical engagement distances. Even when the shooter's eye is not perfectly centered behind the optic, the bullet will still strike close to where the dot is placed on the target.

What is the significance of handgun red dot offset?

Unlike rifles, the mechanical offset between the bore and the red dot sight on a handgun is very small. This means shooters should simply aim directly at their point of intended impact, as the difference is insignificant for practical handgun shooting distances.

What is the best practice for dimming a red dot sight during zeroing?

To achieve maximum precision when zeroing a red dot sight, it is recommended to dim the reticle to its lowest visible setting. This makes the dot appear smaller and sharper, allowing for more accurate alignment with the target.
