There was a similar thread about Laserlyte CS with several very pleased customers. Including me. they might not be the best, and highest priced laser on the market, but their customer service is not exceeded by anyone! Considering that I don't really rely on the laser, and use it mostly as a practice aid, it has served that purpose well on my LCP.
