I checked NO to both, but I wouldn't be opposed to night sights or a laser on my carry weapons.
My primary carry in warm weather is a S&W 637 Airweight .38spl revolver. I do not have a laser on it, but if I could afford it right now, I would get the Crimson Trace laser grips for it.
In colder weather, I still carry the S&W 637 a lot, but I also add a 1911, an XD9, and a S&W 5903 to the mix. None of them has a laser. The S&W 5903 does have night sights, because it was a former police sidearm. If I could afford it right now, I'd get Trijcon sights for the XD.
