I have a 20 guage wingmaster that I was given by my father. I enjoyed this weapon all to much, the blueing is worn off, but the function is perfectly smooth. I have killed more rabbits and deer than I can remember. I need to get it coated with synthetic stock and forearm and a mag tube extension, just for fun. maybe a cantilevered barrel to boot.
Kel-Tec KSG - while I have not had to opportunity to shoot one, the amount of ammo it cares and in its latest version is very reliable (just have to make sure you are not short stroking the pump action). Also being a bullpub makes it a great size and weight for home defense. Reloading is not the best, but with 14(+1) if you have to reload you are hopefully at the range.
