You are getting some great advice Bicholui. The best advice I can give is to see what you can get your hands on and shoot it. I don’t have a preference to DA or SA but some do. Another factor might be if you reload or not. The nice thing about the 44 is that there is a nice amount of “practice quality ammo” that is available to the non-reloader. The 480 is a fine round but it is more expensive to shoot. You might also check with the laws in South America as well to see any stipulations on large boar hand guns.
