If I'm not mistaken they just upped their minimum age to 21. But I'm sure there are plenty of LGS out there perfectly willing to.Try this scenario out.
Female college sophomore living in an off campus apartment. She's 20 and living all alone in a little efficiency apartment across the street from campus. She can't get or keep a hand gun but she can, right now, keep that 20 gauge coach gun that her uncle gave her. Or, if she doesn't have a generous uncle, then she can go down to Walmart and buy a Mossberg 500.
