RE: shot gun for small lady
I work at a comercial range and have seen more people start out shooting in a busy weekend than most will see in years.
IMHO a autoloading shotgun in a 20 ga. (some cases 28ga. is even better). Bite the bullet and spend a few extra dollars on a youth model auto than single shot or pumps. You can alway find a decent one used for a few dollars more than what you want to pay at the moment.
