BigCleo, that is exactly the way my Sig 228 is equipped. The dot rear sight lives in the box. I was a pioneer at TXDPS, in scheduled night time firearms training. My troopers at first thought I was crazy, but we soon learned that a lot of available light existed, even on moonless nights. They
soon got the hang of it and if they could see it, they could hit it. Amazingly, we realized that the glow from even small west Texas towns reached for a few miles. And sure, we worked on flashlight use at times. It doesn't have to be mounted to a gun to be useful. For sure, lights are so much better than they were in the early '70 that there is no real comparison. Again, the front sight is the key.
