Wife just got me an LG436 for my g36. Told her I needed to try it out to make sure it works ok! And yes it does. This is my first laser for any of my firearms and I must say that for someone who needs glasses like myself, they are a definite aid in aquiring a target. I won't use it till XMas (part of the deal), but it sure is nice. I think before I buy any more guns, I might consider putting lasers on the ones I already own. I know there are a lot of people who say don't depend on the laser instead of the sights, and while that may be true, you can't deny the fact that they are a very usefull tool to have.
