Apology accepted.

If you have further, more specific questions, go ahead and ask them.

Know now that even though it is legal to purchase a hand gun from a private party at 18, good luck finding a person who will actually sell one to you. Most people aren't aware that it is legal, and many who are aware, still aren't comfortable selling a hand gun to an 18 year-old. I personally wouldn't sell a hand gun to someone under 21 unless I knew them very well.
