Lake Placid (1999)

M203 Grenade Launcher

Sherriff Keough (Brendan Gleeson) arms himself with a M203 grenade launcher equipped with a folding stock to kill the Crocodile in Black Lake much easier. "Whatevers out there, one shot with this and its dead." He ultimately uses it to dispatch one of the Crocodiles.

Ruger GP-100

All of the law enforcement officers in the film carry these Ruger revolvers as sidearms. Sherriff Keough (Brendan Gleeson) pulls it out and scares Hector Cyr when he investigates a bump in the night. Deputy Sharon Gare (Meredith Salenger) fires her Ruger out of Hector's helicopter window when one of the crocodiles attacks it. Jack Wells (Bill Pullman) also uses a Ruger near the end of the film and fires six shots at the crocodile futiley as it aoproaches Kelly.
