Does anybody have any experience with these. I looked one over at a gun show in Raleigh this past weekend and it looks promising. The laser activates when a person's finger goes inside the triggerguard and touchs a sensor pad. Deactivates in approx. 8 seconds when the finger is removed. Right now they are being made for Glocks, Kel-Tec, and Kahr's. According to their website they are coming out with a model for the XD in July. According to their website the unit is made in the US. It looks like a pretty durable unit, but looks can be decieving.
