It'd be ok if it was the real thing. I had my daughter shooting my 44 Mag, when she was 10 years old. (I stood behind her and had my hands on hers, for support. She eventually ended up shooting it without my my close support anyway, though.) She shot everything in the arsenal and was very proficient with my little Glenfield Model 60 22lr. (Knocking the primers out of 12ga hulls, from about 40 yards.

)
Get that lil girl shootin' for real!
