For girls, unless they have a lot of upper body strength, I would vote for a lighter gun than the 1100. I purchased a 20g. Charles Daly semi-auto in youth size. It weighs around 5 1/4 pounds with an aluminum receiver and I think 20" barrels with changeable chokes. With lighter 20 gauge loads it does not intimidate a youngster and gives them a much better chance of hitting a target. It is inexpensive, around $300 new last time I checked and is black from end to end which kids usually like. There is plenty of time for them to graduate to the guns we like.

So many guns, so little time!
