About the FAS 604
The FAS 604 is a single-stroke pneumatic 10-metre match air pistol built by the Italian target-gun maker Fabbrica Armi Sportive (FAS). Charged by a single stroke of the under-lever, it fires a .177 (4.5mm) lead pellet from a breech-loaded single-shot chamber, and is purpose-built for ISSF 10m Air Pistol competition. It carries a fully adjustable two-stage match trigger, micro-adjustable target sights on a long sight radius, and an anatomically carved hardwood grip. Handmade in small numbers, the 604 earned a reputation as a precise and reliable competition pistol, and its design later evolved into the FAS 6004 sold under the Chiappa Firearms brand.
FAS (Fabbrica Armi Sportive) emerged in the early 1970s as a specialist Italian maker of handmade 10-metre match guns, and the 604 became one of its best-known air pistols among Olympic-discipline shooters before the firm and its designs were absorbed by Chiappa Firearms.

Not a cartridge firearm — the FAS 604 is a precision 10m air pistol firing .177 pellets via single-stroke pneumatic action. It should not be confused with the FAS OP 601, a .22 Short rimfire rapid-fire competition pistol from the same Italian maker.
