The world's most versatile firearm? - My opinion

As far as all the different loads, projectiles, and mechanisms is concerned, I don't think you can get any more versatility than with a 12 gauge shotgun. Tons of different types of shells, from fine bird shot to 00 buckshot, slugs, rubber balls and all kinds of improvised stuff, as well as adapters for different calibers, there is a staggering amount of options.
