I just don't understand why people have to try and fix things that aren't broken.
For two reasons, really: 1) because some people are just tinkerers and 2) because people like certain things they own to be unique or "customized" in some fashion.
I have an LC9 and I can tell you there are a couple of things I'd change on it if I could find or make the right parts. I'd like for someone to develop a laser sight that replaces the loaded chamber indicator, or at least come up with some that have witty personalized "themes" to them - maybe just carve "SKANS" in it.
People are always replacing the doo-dads on their 1911's with custom parts, why not the LC9?
