Nah, it looks fine IMHO. I'd like a set of nice wooden grips BETTER, but these are still "normal" looking enough as to not appear gaudy. The really pad ones are the ones with teh skull and crossbones, or hazmat symbols and such.
I think mother-of-pearl (be it real or just the pattern applied) or other mostly white/grey grips look a bit goofy too, but anything wood-grained or mostly black works for me, so long as they're wood or plastic. Basically any hard material - as much as some love them, I've found that I really, really don't like rubber grips on a pistol.
