I second the King videos (plus it gets you an entry into their airplane sweepstakes) for helping to explain all the nit-picky details. Don't just get their basic set, but also try some of their other titles as well. I think my set was well worth the money.
"A gun is a tool, Marion. No better and no worse than any other tool - an axe, a shovel, or anything.
A gun is as good or as bad as the man using it. Remember that." Alan Ladd as Shane (1953)
