It just works - EOTech EFLX Mini Reflex Red Dot Sight

This is the first pistol optic I've ever tried. I mounted it on a Trybe G19 slide. It's nearly a direct fit but more on that later. The dot was nearly perfectly aligned from the box. I had to make a windage adjustment and it was dead on. The brightness settings are great, the battery access is excellent, it weighs next to nothing and doesn't upset the pistol balance, there's no shake or blur. It's really a good optic. Now, the one probablem I have is the included screws don't fit my slide. They were far too fat. The Trybe screws were the right thread pitch but too long and too large head diameter. I had to modify the Trybe screw length and the diameter of the head and it fit up perfectly. If I had an M17 it might have been plug and play, I don't know. I really like it after my whole life of iron sights. It doesn't obscure the target and it was really easy to get used to. Wouldn't recommend trying to carry it inside the waistband.
