Sololucky - Your having the casings flying to different places may sorta narrow the problem down (assuming that the chamber is pretty clean when all this happens). If you hare having failures to extract AND the spent casings are not landing in about the same place, there's a good chance that the problem is the extractor. Take a look at its little tooth close up and see if maybe it's rounded off or broken. If you can't see anything obviously rounded off, then it is likely that the extractor's tension or length isn't right. I'd take it back where I bought it, explain to them that you know these are distinct possibilities based on (1) FTEs and (2) brass landing all over the place, and see what they'll do to make it right.
Sorry you're having trouble with your Micro. I flat LOVED mine - out of the box it was slick and accurate - not a single bobble with any of the ammo I tried. The only boo boo I noticed about mine was that the factory lettering on the side got really shallow in places. Sold it to a friend who needed it more than I. Otherwise I'd still have - and still be carrying - it.
Oh, and one more thing. This'll sound weird, but I'll try to explain - when you try the pistol again, grit your teeth, and get pissed off. Sounds funny, I know, but I remember when I have had guns that I wasn't too sure about, I'd try getting dirty dog mean, and try to "dominate" the pistol. Hold the sonofa)@$#)(* hard with a crush grip! (That'll be what you'll have on it anyway if you need it for defensive purposes, and it won't affect accuracy much at practical ranges.) Doing that may get you past not only possible limp-wristing (which you may or may not be doing) but also may make you discover some things about where your concentration is during firing that may be adding to what's throwing things off. Really run the gun hard for a few hundred rounds. The break-in might also help it function better.
