Picked one of these up for a good price at my local gunstore but when I got it home I was, to put it mildly, unimpressed. The intensity of the light was below what I've come to expect from a 3-volt xenon light and the beam could not be focued - it seems to be a poorly shaped/molded reflector. I've since gone back and checked several others of the same model in stock at the store and find they all have the same issues. While the fit and function of the switch is good, the low output and poor focus are two issues that will keep me from buying another. Sorry if this seems like Glock bashing, but it's not (I own 3 pistols and love them). Just an honest evaluation of a product's performance.
