SureFire's XC1-B Compact Handgun Weaponlight was developed to be as compact and capable as possible and intended primarily for concealed-carry use. SureFire’s smallest and lightest weight weaponlight has been upgraded to deliver more output and feature improved switching based on feedback from subject matter experts. The XC1-B has an output of 300 lumens and is capable of one-handed constant-on activation.
Ambidextrous switching provides both momentary and constant-on activation options. Momentary activation is achieved by placing your support hand thumb on top of either of the two rear downward-activated switches and pushing down. The XC1-B will stay in momentary mode for as long as either toggle switch is depressed and held in the on position beyond a fraction of a second. Constant-on activation is achieved by quickly tapping either one of the momentary switches. To turn off the constant on mode, quickly touch and release either toggle switch. Constant-on can also be achieved by using your support hand to push the center crossbar switch from left to right.
