I've been disappointed by lighting options for pump shutguns. I love the actual light on the surefire DSF, but the short length of the forend, coupled with the strange almost reverse grip angle made it next to unusable for me.
I would love for Streamlight to make a better forend than this. That's what I was hoping for, but everything I've seen has been negative.
I guess the Magpul forend + Surefire scout is still the best.
