Mounted to a XD-s 9mm, I gave this a 4 star rating, because it was a millimeter to long, so the back of the laser makes slight contact with the trigger guard, this results in a slight misalignment on the rail, forced it backwards hard and it did allign and mount, not with complete confidence. Plastic pic rail grip, so low expectations, bright light/laser. Great for non self defence use. [Source : Wish]
