The laser has in most firearms applications been used as a tool to enhance the targeting of other weapon systems. For example, a laser sight is a small, usually visible-light laser placed on a handgun or a rifle and aligned to emit a beam parallel to the barrel. Since a laser beam has low divergence, the laser light appears as a small spot even at long distances; the user places the spot on the desired target and the barrel of the gun is aligned (but not necessarily allowing for bullet drop, windage, distance between the direction of the beam and the axis of the barrel, and the target mobility while the bullet travels).

Most laser sights use a red laser diode. Others use an infrared diode to produce a dot invisible to the naked human eye but detectable with night vision devices. The firearms adaptive target acquisition module LLM01 laser light module combines visible and infrared laser diodes. In the late 1990s, green diode pumped solid state laser (DPSS) laser sights (532 nm) became available. Modern laser sights are small and light enough for attachment to the firearms.

In 2007, LaserMax, a company specializing in manufacturing lasers for military and police firearms, introduced the first mass-production green laser available for small arms. This laser mounts to the underside of a handgun or long arm on the accessory rail. The green laser is supposed to be more visible than the red laser in bright lighting conditions because, for the same wattage, green light appears brighter than red light.

Laser are effective tools when used properly, but the following guidelines should be observed when using them:
Never look directly into the laser beam.
Never point a laser beam at a person.
Do not aim the laser at reflective surfaces.
Never view a laser pointer using an optical instrument, such as binoculars or a microscope.
Do not allow children to use laser pointers unless under the supervision of an adult.
Use only lasers meeting the following criteria:
1. Labeled with FDA certification stating “DANGER: Laser Radiation” for Class 3A firearms lasers or “CAUTION: Laser Radiation” (Class 2 pointers)
2. Classified as Class 2 or 3A according to the label. Do not use Class 3B or 4 products.
3. Operates at a wavelength between 630 nm and 680 nm.
4. Has a maximum output less than 5 mW; the lower the better and more safe.
