How young is too young?

[1911KY]

I have been thinking about getting my daughter out to the range to learn how to shoot but I still think she is too young yet at the age of 3.

My buddy has a daughter of similar age, just turned 4 and he let her shoot his sons .22 pistol with assistance of course.

I know she would love it as she always wants to go shooting with me but she isn't to fond of loud noises yet.

What do you all think?
