FN "Five-SeveN", 5.7x28mm cal. semi-auto pistol. Serial #386105403, mfg. Belgium.  Excellent perhaps test fired in factory box with all accessories.  This is the little gun you've heard so much about!   Rumors abounded early in its introduction with this hot 20+1 high capacity. Rail under slide.  Very light with polymer frame and alloy/plastic construction.  Textured grip areas.  Gray control levers against black finish is a nice touch.  4 1/2" barrel with three-dot adjustable combat sights.  Hard factory box with manual and paperwork. Nothing else quite like it!
