Man... you might be best to buy one brand new. Most (if not everyone) that I know who has one won't get rid of them. They are great. Good look in your hunt, if you find one you will love it! Be sure to get an aftermarket barrel with better chamber support if you plan to reload. (if near Abilene, I have seen 2 in Wild Bills Pawn as of last week).
I ordered a G20C in March. It just came in today. $505 LE price. I will pick it up tomorrow. I do not know if they got anymore in. I was told two weeks ago it was scheduled to be built the second week of September. There may be a run coming soon.
