A new study published in the journal Pediatrics shows PG-13 rated movies feature the most gun violence in the entire rating system.
Movie goer, Alvin Pierce says he's noticed a big difference, "it's definitely increased from the time I was a kid to now and over the last 5 or 10 years, it's up its a lot more than what it has been and what it should be."
The study shows the amount of gun violence in PG-13 movies has tripled since 1985 to 2012.
In R rated movies, the rate has stayed the same. For G and PG rated movies, the amount of gun violence has dropped.
The new finding is causing many parents to resort to tougher rules when it comes to flicks marketed to young teens.
Parent Renee Garden says she will, "not let her see those movies, just keep her away from it."
Another parent, Abraham Hernandez, says, "there's plenty of violence for kids and it's inappropriate for them to watch, we just stick to cartoons and that's it."
The concern from psychologists is that young teens may mimic what they see in violent movies.
While the Motion Picture Association of America sets the ratings, it may be better for parents to decide what's best.
"I think the MPAA is going to have to take a cold hard look at what sorts of films get a PG-13 rating." says
