Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon P300 is 5g lighter than the Nikon P310 but we don't think this will make a significant difference.
Weather Sealing
Unfortunately neither the Nikon Coolpix P300 nor Nikon Coolpix P310 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Nikon P300 and Nikon P310's LCD screens have the same diagonal size of 3.00 inches.
