Actually, Streamlight is coming out with a forend unit next year. I saw a demo unit at the last gun show and also at my local gun shop. Very nice unit with pressure pads and an on/off that disables the pads. As of now (talk to Streamlight directly about this), they will be in full production sometime next year and only available for Mossbergs to begin with. I'll be waiting for them to make a Remington 870 version because it feels much more comfortable than the Surefire unit in my opinion. No foreseeable smack from the unit.I tend to agree with this, but in this particular case its only because Surefire is the only game in town that integrates everything into one unit. If Streamlight did something similar then I'd recommend that.
