ABSTRACT:
A laser sight that can be concealed within a standard autoloading handgun. The invention features a chassis that is mounted to the front face of the slide of the handgun. The chassis has the same cross-sectional profile of the handgun and extends the slide by only about three quarters of an inch. Therefore, the handgun can be carried in standard holsters. The standard spring recoil guide is replaced by a novel battery pack designed to be used with commercially available batteries providing about 12 hours of operating time. The device is activated by a three different membrane switches, one on the chassis itself to select between an infrared laser, a "red" laser, and an incandescent light; a second membrane switch on the trigger which activates the sight when a slight pressure is applied; a third membrane switch located on the side of the frame so that the sight can be activated without placing a finger on the trigger. A delay feature is featured with the third switch so the user can move his finger from the frame switch to the trigger switch without the sight being turned off.
