I'm planning on mounting the PILA GL3R on my benelli Nova. Surefire doesn't make a dedicated forend for the benelli. I would prefer the GL2R as it uses one battery and would be more "recoil" resistant, but PILA doesn't make a long enough tape switch. The GL3 will provide about 100 lumens. I tried to contact Surefire and couldn't get an answer concerning a tape switch for the G2, I would use that with a PILA 168s and a tape switch if they make one long enough for a pump gun.
