I snapped some pics of CrimsonTrace's New LightGuard for the 1911. This is a nice light for around $150. I only had one issue with it; when I would gain a sure firing grip on the pistol I would only partially activate the pressure switch causing the light to flicker. The light is still amazingly bright for such a small package. Below are some pics of the LightGuard mounted on a Kimber Ultra Carry II outfitted with a CrimsonTrace LaserGrip.
Gunmart Blog has a closeup look at the LightGuard as well!
