Its threaded barrel offers compatibility with muzzle devices or suppressors where legal, and the adjustable sights plus fixed barrel support consistent accuracy for target work. If you value a lightweight rimfire pistol for range practice or casual plinking that mirrors the controls of larger centerfire service pistols, the FireFly is a focused option in that role.
