When I was at Blackwater, I spoke with Patrick from Crimson Trace regarding green lasers. He mentioned the drawbacks of them (basically you have to filter the laser, making it somewhat wasteful on energy) as well as the plusses (visibility being one of them) and said they were working on some stuff at the time.
Looks like that time has come.
Awesome! Unfortunately, my evil plans to procure a KRISS turned into kitchen cabinets and granite countertops, so I won't be able to pick up a Crimson Trace foregrip in green for a while, but rest assured, if I ever do get my mittens on the Super V, I'll be grabbing one of those for sure.
