Actually, in a lot of circumstances, the Kalashnikov is poorly used by people who are not especially good shots, or who are outright bad shots. In these cases, the rifle's weaknesses emerge. As far as accuracy goes, the Kalashnikov is stubbornly mediocre, and the ease with which it can be fired on automatic means that many people fire it on automatic when they would be better served firing a single, aimed shot. Getting shot at by a sniper is a much different experience, and far more frightening. But either experience is, to borrow your word, memorable. These memories are pretty much all bad.
