There were some Fw 190 models that had lots of guns. D12, D13, or something. Some Bf 109Gs were built with motorkanone, machine guns on the nose, and 2 kanone in the wings. I guess those were supposed to be bomber killers. A few 109s with wing guns came to Finland but the guns were soon removed. The pilots needed to be able to attack everything, and take evasive action. They felt the wing guns made the 109 too sluggish.
