No, the slide isn't going to break. Oddly enough guns shouldn't be used as a sledge hammer. Under normal use it's fine. Take a look at all the custom milling jobs on slides. Much more removed but still not going to break. Wherever you read that they are yanking your chain. If you are planning on keeping it stock, go 2.0. If you're going to put a trigger in it and like the texture of the 1.0, no point in the 2.0 at that point. I have a 1.0 with apex trigger in it. My grandfather has a stock 2.0. I don't mind either but prefer the apex either way. The grip is negligible to me.
