This guide explains the SIG Sauer pistol sight numbering system, crucial for accurate firearm zeroing. Instruction from Brownells' technical staff highlights that higher sight numbers increase point of impact, with specific adjustments for front (1 inch/number at 25 yards) and rear sights (2 inches/number at 25 yards). Understanding these numbers and their location on the sights ensures proper firearm tuning.

Quick Summary

The SIG Sauer pistol sight numbering system dictates point of impact adjustments: higher numbers mean higher impact. Front sights adjust about 1 inch per number, while rear sights adjust about 2 inches per number at 25 yards. Numbers are stamped on the sight components, typically on the dovetail base (front) or sight body side (rear).

Frequently Asked Questions

How do SIG Sauer pistol sights affect point of impact?

The higher the number on a SIG Sauer sight, the higher the point of impact will be. Conversely, a lower number results in a lower point of impact. This system allows for predictable adjustments to zero your firearm accurately.

What are the adjustment values for SIG Sauer front and rear sights?

For SIG Sauer sights, each number change on the front sight represents approximately a 1-inch shift in point of impact at 25 yards. On the rear sight, each number change corresponds to approximately a 2-inch shift at 25 yards.

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

Sight numbers are typically stamped directly onto the firearm components. Front sight numbers are usually found on the dovetail base, while rear sight numbers are commonly located on the side of the sight body itself.

Are SIG Sauer sight numbers consistent across all models?

The numbering system is generally consistent across most SIG Sauer pistol lines, including the P226, P320, P938, and P238. However, exceptions exist, such as with 1911 models and the P210.
