As far as a weapon-mounted light, I would recommend the Streamlight TLR-2 HL-G. It's a rail mount, 800 lumens, green laser, and at a very good price. They are fabulous folks, and Streamlight supports the Concerns of Police Survivors programs that provides support and assistance to the families of officers killed in the line of duty. There are great quality light/laser combos on the market from several companies, I like to support companies who support the same things I do. BTW, I purchased one of these for my wife's new Sig P320, and it's awesome. http://www.streamlight.com/en/products/detail/index/tlr-2-hl-g
