A firearm laser training system of the present invention includes a target assembly, a laser transmitter assembly that attaches to a firearm, a detection device and a processor in communication with the detection device. The system simulates targets at extended ranges and accounts for various environmental and other conditions. The target may be in the form of a target image or a display screen. The detection device captures images of the target for processing by the processor to determine beam impact locations. The processor applies various offsets to the beam impact locations to account for the various conditions and determine the impact locations relative to the target. The processor displays an image of the target including the determined impact locations and scoring and/or other information that is based on those impact locations. An electronic laser filter may be employed by the system to minimize false impact detections.
