If you're clean Antn, then a firearms permit is an option.
Once a permit is obtained you can have for example a 7 shot S&W .357 under your bed, in a locked box, with ammo next to it, also in its own locked box.
The only time you'd be able to use the .357 is at a registered range. It's even illegal to use such a firearm if you're legally hunting.
Apart from that you could try out the Colt .45 but you'd need to migrate to Gods country
