44 pistol may be found in Hardware Town on a table with a box and wine bottle in a room upstairs. Follow the pump pipe, it leads directly to the skeleton with the gun. Cross the bridge leaving Sanctuary then follow the shore left, past a dock until arriving at the water pump. The skeleton is leaning against a deactivated water pump not far from an unmarked small raider camp. A snubnosed version of this revolver can be found in the water filtration caps stash lying beside a skeleton close to the shore of the lake near Sanctuary, but before Concord is reached.
