The woman whom Vice President Biden urged this week to “buy a shotgun” for protection says the idea would likely backfire and suggested that the advice sounded sexist.

Biden made the recommendation during a Facebook chat on Tuesday, saying he has advised wife Jill to stand on the deck of their rustic home and fire the family's double-barreled shotgun in the air, should she sense an intruder.

“It was poor advice, and it comes off a little sexist,” Kate Ernest, the woman who got the advice, told Fox News Channel on Friday.

Said Biden: “You don’t need an AR-15 — it’s harder to aim, it’s harder to use. You don’t need 30 rounds to protect yourself. Buy a shotgun.”

Biden used the social media event to garner public support for President Obama’s attempt to tighten federal guns laws, following a series of mass shootings.

Among the recommendations are to ban assault weapons and high-capacity gun magazines.

Ernest purportedly has a small cache of firearms that includes an AR-15. She said a double-barrel shotgun holds only two shells, which would make a shooter a “sitting duck” and that he or she might easily fumble while reloading should somebody be attacking them.

Ernest said Biden’s advice also sounded like: “Let me tell you what you need versus arm yourself and protect yourself with what is necessary.”
