Abstract: A laser target pointer for engaging a gun includes a body, a locating plate, a positioning block, a first fitting element and an adjustable positioning assembly. By providing the adjustable positioning assembly, the laser target pointer can be clamped to a gun with an arbitrary body width. By adjusting a position of the positioning block with respect to the locating plate, the laser target pointer can be positioned to a gun with an arbitrary transverse positioning groove. Thus, the laser target pointer can be properly assembled to any gun body having specifications within a predetermined range, and the position of the laser target pointer can be adjusted on the gun body in the extension direction, such that a single laser target pointer can be applicable to various guns with different brands, types, series or specifications.
