Last year I was at my local pizza joint owned by 2 brothers. We chat about guns, so when the store was empty, he pulls out a used Glock he had just purchased. While it was clean, it was dry as a bone. I said I could not let this stay this dry, but he had no gun lube at the shop. So I lubed it with olive oil. Now I wouldn't do that on a normal basis, but it worked. GARY.
