So I have a J frame 442 sitting in the safe since 2009. It hasn't been fired but I want to give it to my wife now that she is starting to get into shooting and getting her CCW permit. Does anyone know anything about D&L sights? Or would you just recommend a laser? She shoots by g19 well but she won't carry something that big on her. She'll have to get more range time with revolvers but she prefers the size. Any ideas?
