I had my CM9 out again today. I really like the way it shoots. I still don't have quite 100 rounds through it yet and it is still flawless as far as function goes, but my question is...How much wear should I expect? I'm not really used to plastic guns. The frame has little plastic shavings on it were the metal slide drags on the plastic rails and at the very back of the frame, it just knocked a piece of plastic out. The peice that was knocked out had no function, it was just filler for cosmetic reasons. Just curious how long it will last if it keeps shaving plastic.
