All of my guns have a loaded chamber indicator. It's north of my eyebrows.
Not to be flip about it, but LCIs are another mechanical doodad that can be nice to have, but are no substitute for knowledgable and safe gun handling. My first auto was a Sig P232 that my father gave me when i got my carry permit. Technically on that gun you can feel the extractor and feel it bumped out if there is a round chambered. Even at the ripe of age of 21, I knew better, and simply did a chamber check. I can look and feel for myself. An LCI is really not a selling point at all in my book. An LCI, like any mechanical safety, can fail, so I do not count on it.
It's actually one of the reasons I like that little port in the top of my S&W M&P. I can simply look down into the chamber and see it for myself.
The ergos are just wrong FOR YOU. Doesn't mean they are wrong for everyone. I happen not to like them, and I feel they are wrong for me too, but there are lots...and lots....and lots...and lots...and lots...and lots.... and lots of people who do just fine with Glocks.
