Lasers continue making inroads into the firearms market. I think for smaller handguns they are especially valuable, as the iron sights are frequently abysmal. And prices are really dropping, in some cases about even with the cost of a good holster.

However, please do not use a laser sight mounted on a handgun as a pointer during a presentation as the NY State Director of Homeland Security did.
