I was cleaning my G17 yesterday when the small, thin disc broke off of the guide rod. I know Gen4s are under an RSA recall of which mine was not covered, but Glock is sending anyway since I've possessed the pistol for less than a year. My question is this: are there any other Glock owners that have swapped out an RSA for an aftermarket one (e.g. Lone Wolf)? If so, any recommendations?
