Well, She's too intimidated by shotguns so that's out, we're both too young for a handguns (19), I have a Mini-14 that I love but it's to heavy for her, I figured a carbine would be the best all around rifle for her, but a 9mm AR would be great too
Hi point has some nice ones. I have the 995ts. I paid 300 for it. They come in 9mm .40cal and 45acp. If anything ever goes wrong with it hi point will fix it no questions asked.
I hear jr carbines has some nice ones too. They are around the $1000 mark though.
