Jenn, you have a S&W autoloader? I never liked any of 'em

I used to shake my old 4506 as a tambourine. You could hear the slide rattle rattle rattle.
Never had a problem with S&W's wheelguns, tho.
BTW, I think the US Postal Service frowns on mailing handguns (it's illegal). Fedex and UPS or other courier are the way to go.
