What do you do when kids pretend to shoot?

Curious what other parents/educators think about topics or play that come up while in school. Guns are everywhere in the US & most kids play with them but not in my class. I tell them that guns are tools for grown ups, not toys & if they struggle I'll compromise & say water squirters & they have to make water noises. 😂 That usually squashes it & I get a laugh at them being dorks making water noises. What would you do if you were a teacher & kids started playing "guns"?

I am not a parent. I don't want to overstep my boundaries so I don't want to tell them they are wrong. I just don't want to normalize kids playing with guns. 🤷
