I started changing to steel anything on all my guns years ago. Use to have pics of some really chewed up both recoil and striker guide rods. Here is a latest one from a Ruger SR9C. Hard to tell from he pick, but there is significant damage to the Plastic guide rod. (and this one is no where near as bad as many I have replaced)
I replaced it with steel from Gallaway. The small guns like 380's seem to take the worst beating.
