I bought this "new open box" but never ended up using it. This is the LG-626 for Glock sub-compact G26, G27, G28, G33 & G39. But it is the exact same size as the G19 version (I'm not sure what is different - fits on my G19 fine) This laser is neat because you don't need a special holster, since the laser is on the side. This was put on, and then removed and placed back in the box. Works good and comes with box and goodies.
