I believe the word has meta-morphed in to the current form after years of lost translation.
Over a century ago in the wild wild west, a gun was called a "Peace Maker" and was strapped to the hip by a holster. Therefore, whenever it was mentioned, it was referred to as the "Peace."
Somewhere along history, I believe that people lost the original translation and started referring to the gun as a "piece" instead of the original origin "peace."

Yes, although the US Military likes them to be called a rifle, a weapon, or a piece- and machine guns, shotguns, and cannon are called guns. But yes, the term gun and firearm both mean the same thing. All rifles are guns, but not all guns are rifles.
