Where I come from if you don't shoot a 12 you ain't shooting a real gun. 'Course, it has to be an auto - or a pump if you're a second-class citizen - and if that 12 will handle 3" mags, so much the better. 20's are for kids or girls, and 16's...why hell; nobody shoots them old relics any more. Can you even get shells for 'em? 12's are real popular here...so long as you can stuff 4-5 shells into 'em
