I want to bring my brother to shoot. He is 20 years old. Can he shoot or does he have to be 21?

I took my son there few times and he was able to shoot and his only 13.

Actually they let children shot if accompanied but an adult. I go there all the time.

Shooting age is 18 so he is good, but he must have ID.

Also long as you are 21 or over, then you can let someone shoot your pistol there. With you present, of course.
