C-MORE SystemsSerendipity Red Dot Sight with Click Switch (Frame Width: .750-Inch)

I have 3 of these now. Absolutely love them. The click switch is worth the extra money as my earliest sight with the regular switch began to fail to turn off. Nice bright dot if needed even in blazing sun. Finding the dot becomes second nature. A quick way to find it when new to you is to let the hood of the dot module cut into the bottom of the lenses sight picture and the dot will be right there. Also, a good way to get on paper with a 1911 is to remove the firing pin, carefully put the gun in a padded vise, cock the hammer and look through the firing pin hole like a peep hole sight and match the red dot sight to whatever you're looking at through the hole. The length of a 2 car garage worked for me. It got me 2 inches from bullseye both windage and elevation. Similar method works with AR sighting through barrel. Great sights.
