Raimey, good on the photos. Set the camera on closeup [macro] which is sometimes denoted as a flower on the camera setting dial. Then use a medium or dark background material to lay the gun on. Do not use a flash or direct sunlight. Indirect sunlight like a north window works well, or just take the pictures in the shade. Your camera should be able to do the rest. Some cameras let you push the shutter button half way down before you take the picture. This lets the camera adjust itself to the scene and take sharp images.
