I've got a Streamlight Model TLR-2 S that fits perfectly on my SIG Model 226. The LED light is blindingly bright and the red laser is easy to pick up. The activating paddles are easy to access and you have a choice of laser alone, light alone or laser/light combined (my favorite configuration). The unit comes with a strobe feature (ergo, the "S") but it takes a lot of practice to deploy it effectively. I haven't had the unit long enough to review its durability, etc., but, so far, it's everything I wanted out of a light/laser combo. If you're interested in buying one, Nachetz currently has them on sale for $241.99, plus $17.23 shipping (to Ohio); which is a pretty fair price based on my shopping around "research".
