My 2nd gen G20 still had that copper lubricant in it too, it came to me unfired and minty new. I was also told that I could trade my early G20 for any Glock I wanted, apparently they are something of a collector's item, from what I'm told they are pretty well sought after piece's.
I also like that my Glock coffee mug has my "early Glock 20" on it too.
BTW, the manufacture date on mine is 1995 so it wasn't manufactured during the recall period.
I also prefer the dull parkerized slide finish and the absence of finger grooves, not that I don't like the 3rd gens, I just like the classic look better, as I do with most things but I'm from the old school, whaddya want from me?
