I personally have no arbitrary limit on the number of guns a person should be allowed to own, however it makes zero senses to me why anyone would want multiple copies of the same gun. now, I own 4 AR15s, but, every one of them is a different caliber, some are carbines, some are rifles, some are open sighted, some are scoped, some are free floated, some light, some are heavy, all serve a slightly different role. I think I would do the same with a 1911. I own a springfield range officer, I love it, it shoots great, it's enough 45ACP 1911 for me. I think if I did get another, it would likely be a 9mm/22tcm combo from RIA. I have no use for two handguns that have the same controls, ergonomics, and shoot the same caliber. variety is the spice of life, so I've been told.
