They make a "polymer safe" version and I use it on my Glocks and MP. I haven't had any

problems on mine, but I make sure to wipe off any excess before it dries. I also remove the

grip panel because I don't know what it would do to that material.

It is listed as "polymer safe" on the can....I forgot to mention that.
