I'm a simple guy. None of my guns have anything but iron sights. Red dot and holographic sights seemed about the same to me so I looked up an article or two. What do you guys think about the authors assessment of the differences? Looks like my pistol will get a red dot if I do this. Long guns don't seem worth it for me.
One more thing to case and bump into things. Is this guy telling me good info?
