A laser sight for a firearm (10) having a recoil spring guide (15) mounts components on the spring guide so that a light beam (18) is directed along the axis of the spring guide. This automatically makes light beam (18) parallel with the barrel (11) of firearm (10). Several mounting alternatives are possible, including a collimating lens (21) arranged on the axis of the spring guide to receive light from a laser diode (20) that is either mounted on the spring guide with the collimating lens or mounted remotely and arranged for directing light to collimating lens (21) via a fiber optic cable (25). These arrangements can also conceal the laser light within the firearm, where it is well protected and not noticeable. |
