The front sight of the M9 Pistol is classified as what type?

The front sight of the M9 Pistol is classified as fixed. A fixed front sight is integral to the slide and does not move or adjust for elevation or windage. This design provides a consistent aiming point and enhances reliability, as it remains properly aligned during use.

Many military and law enforcement pistols, like the M9, favor fixed front sights because they minimize the potential for damage or misalignment during handling or stress. This contributes to better overall accuracy in a variety of shooting conditions. In contrast to adjustable, collapsible, or detachable sights, which can offer flexibility in certain contexts, the fixed sight ensures that the shooter can focus on target acquisition without needing to make adjustments before each shot.
