Probably the first thing would be to detail strip and clean/lube some of the most common autoloader pistoles. Most 1911's, a Ruger Mk II, Glock, BHP. Now when I say detail strip, I mean down to the grips off and pehaps as far as the firing pin out. This will have you using the correct tools (pin punches, screwdrivers that have been ground correctly to remove and replace screws, bench block). You will also learn alot about putting 'em back together, which is a real problem for some folks. You'll also learn about what makes most of the misbehave - crud in the works. And I've never seen anyone disappointed because all there problem child needed was a good cleaning!
