I just bought some big dots for my gen 4 g23 (ccw), fairly easy install btw. It seems like there is a lot of mix views on them. Some people hate them, some love them, some don't think they're good target sights, etc. Why do you hate them or love them? Why are they not considered target sights? I haven't had the chance to fire them yet, but will soon... just want to get some more detailed opinions on them first. I bought them for ccw given how they're suppose to be quick to sight for close combat situations.
