If you're gonna be using a rubber sleeve of some sort, like a Hogue for example, you're better off replacing the entire grip for one that is already rubber over-moulded...ERGO, Hogue, or one of Magpul's enhanced grips. I've messed around with various sleeve options and have found that they all generally move out of place. It becomes quite bothersome to always be readjusting the position of the sleeve...not worth the hassle, in my opinion. Go with a proper grip which already has rubber incorporated into it...you will not be disappointed.
