The Crucible Industries Ember-9 is a compact semi-automatic pistol chambered in 9x19mm with an integrated visible laser designator and weapon light in a single under-barrel unit. The laser and light activate simultaneously when the shooter's grip engages a pressure switch on the front strap, providing instant target illumination and designation in low-light conditions.

The Firefly is designed for the security professional who operates primarily in the dark — overnight building security, parking structure patrols, residential compound perimeters. The integrated light eliminates the need for a separate handheld flashlight, and the laser provides a visible aiming reference that works faster than traditional sights in the stress and disorientation of a sudden nocturnal encounter.

Crucible packages the Ember-9 with a quick-draw holster specifically molded for the light/laser unit and markets the complete system as a 'night-shift package.' The combination has become standard equipment for contract security firms operating the overnight shift in Mid-tier commercial districts, where the visible laser serves double duty as both aiming device and deterrent — most would-be intruders reconsider their plans when a red dot appears on their chest.
