zero

A specific distance, firearm type, sighting system, and purpose define this concept. Fifteen yards represents a common practical distance for handgun engagement. “Pistol” specifies the firearm category. “Red dot” refers to a non-magnified optical sight projecting a red aiming point onto a lens, enabling faster target acquisition. “Zero” denotes the process of aligning the sight’s point of impact with the point of aim at a predetermined distance. A paper or electronic device displaying a designated aiming point serves as the target for this calibration process. This process ensures accurate shot placement at the intended range.

Establishing a precise point of impact at a relevant distance is crucial for effective pistol use. A correctly adjusted sight allows the shooter to quickly and accurately engage targets, enhancing self-defense capabilities or improving competitive shooting performance. This standardized process builds consistency, allowing for predictable results and reducing the need for holdover or hold-under adjustments at the specified range. While longer zeroing distances are common for rifles, shorter distances like 15 yards are more practical and effective for handguns due to their ballistic characteristics and typical usage scenarios. This process has become increasingly relevant with the rising popularity of red dot sights on pistols.
