FIAS stands for "Fabrica Italiana Armi Sabatti", so the gun was made by Sabatti in the Gardone (Val Trompia) region of Italy. Sabatti is an old-line Italian gunmaker, and their guns are now being imported by European American Armory (EAA).
The Sabatti guns imported by Kassnar and now by EAA are good-quality guns without the expensive hand-fitting and engraving of the higher-end models. As long as you maintain it properly, it will last a lifetime. Be careful, though, as parts availability is almost nonexistant.
The autonomic nervous system provides for involuntary muscle function - the work of breathing, digestion, and so forth. On some folks, that's a pure waste of ingenuity.
