Federally, it is perfectly legal for her to possess a handgun under the age of 18 so long as:
-she is on private property where the owner is ok with it (like your home)
or
-she is under your direct supervision
or
-she is engaged in legitmate sporting events with it and has your permission, i.e. hunting or formal (club, association) target shooting. Parental/guardian supervision is not required under these circumstances.
No federal minimum age for possession of long guns.
Post #12 pretty well covers it.
Respectfully, Art....post #12 contains erroneous information. This is the actual Federal law (notice the "and" that I highlighted). All four conditions must be met, (i), (ii), (iii),
AND (iv) and there is no
single exception for on private property or under direct supervision.
