Understanding the SIG Sauer pistol sight numbering system is crucial for accurate zeroing. The core rule is that a higher number on a sight results in a higher point of impact. Front sights adjust 1 inch per number at 25 yards, while rear sights adjust 2 inches per number. This system is consistent across most SIG models, excluding the 1911 and P210.

Quick Summary

The core rule for SIG Sauer pistol sights is that a higher number means a higher point of impact. At 25 yards, front sight numbers adjust impact by ~1 inch per number, while rear sights adjust by ~2 inches per number. This system is common across most SIG models.

Frequently Asked Questions

What is the basic rule for SIG Sauer pistol sight numbers?

The fundamental rule for SIG Sauer pistol sights is that the higher the number stamped on the sight (front or rear), the higher the point of impact will be on the target. Conversely, a lower number results in a lower point of impact.

How much does each number on a SIG sight change the point of impact?

At 25 yards, each numerical change on a SIG Sauer front sight adjusts the point of impact by approximately 1 inch. For the rear sight, each numerical change adjusts the point of impact by approximately 2 inches at the same distance.

Which SIG Sauer pistol models use this sight numbering system?

The SIG sight numbering system is consistent across most of the SIG Sauer line, including popular models like the P226, P228, P320, P938, and P238. However, exceptions exist, notably the 1911 models and the P210.

Where can I find the sight numbers on my SIG pistol?

Sight numbers are typically stamped directly onto the firearm's sight components. You'll usually find the number on the dovetail base of the front sight and on the side of the rear sight body.
