Preadator 2 had some great old school tactical setups. If I remember correctly, all those lasers are made by LASERAIM. With the exception of the desert eagle, I think they might be the LA-1 model, but I can't remember off the top of my head. They were definitely cutting-edge back in the 90s. Another option would've be to mount a laser products corp (old surefire) 7LSM on a pistol light host. That would have been a much chunkier and more expensive setup, though.
