Ive heard that the rem. 870 is the best pump shotgun u can buy. I think its waterproof. my friend told me a story of wen he was hunting ducks in a swamp and he accidently dropped his gun in not very deep water, but water nonetheless. A duck got startled and flew bcuz of the noise, he saw it, chambered a shell and shot it with no trouble at all. I dont know if this particular model can withstand water damage and surface rust or watever, but he told me it handled smooth as silk wen he shot it.
