Strange how fortune works.....had a flakey seller in the GT classifieds set off a chain of events that led me to a minty 3rd gen G20 priced $400 with the box (plastic) extra mag and all. So I'm happy. Anyways, I'm a 10 millie owner now, so I have a few questions; 1) Is the g20 awesome? 2) Any off the shelf ammo I should avoid with the stock barrel? 3) Should bulged brass concern me?
