My sidegrips were still latched on, but the rubber was delaminating from the plastic. After probably 5 set of replacements every month or so, my warranty finally ran out and I was left with bubbled up side grips.
So I removed the side grips completely and went bare for about a week. I didn't really like how my 2215 looked or felt. So I took the side grips with the half bubbled rubber material and pulled the rubber off. It took minor effort to peel all the stuff off and scrape off the stuff that stuck to the plastic with my fingernail, but when I was done, I had two rubber free plastic side grips. They have little bumps and divets in them from the molding machine, but now that they're back on my 2215, they look a heck of a lot better than being bare.
To tell you the truth, it doesn't look much different than the original rubberized ones.
