Lightest grip for a G19

Pretty much every single company has a version of a dog leg/no step flat bottomed grip for G19s, but I'm wondering what the lightest ones are (not necessarily the thinnest) and if anyone has ever taken theirs apart, how did you find the process? <br><br>I looked at the Moe Lite from Magpul, but at 4oz, that is not exactly the lightest.
