I found an ACE hardware near my house. I don't know what their stance is on firearms, but they have been far more helpful and knowledgeable than any Home Depot or Lowes I've been to. They have a surprising amount of stuff in stock too. I thought being a smaller shop I might run into them not having what I need, but so far so good. Then again I don't build houses, but they seem to still believe in the concept of customer service.
