Yes, I did.  Both of them had cap guns at one stage.  They were more for the loud bang that they made rather than used to shoot like at another person.   They both had super soakers and the one where they can score points.  I can't remember what it's called but it was like paint ball but without the paint.     At around four years my younger one chose a cow boy show bag that had a rifle in it.   He loved it to death because it made a funny clicking sound when it was reloaded. Not that it had any bullets.

Where's the fun in that ? :^O
