The Merr-Sonn Model Q4 "Quickfire" was a hold-out blaster. The Quickfire was intended to be designed around a power pack rather than energy cells like most hold-out blasters are. Unlike a previous model that attempted this – the lackluster BlasTech HSB-200 – the Quickfire succeeded in doing this. As a result, the Quickfire did not reload like most hold-out blasters (by replacing spent energy cells); it had to hook up to a power source via a special cable included with the weapon. This recharge took only ten minutes.
