This is a really well built sight that performs very well. Couple of things I was having trouble with the biggest one being that trying to use the standard sites with the red dot site is a lot more difficult than I was led to believe. Number two the front of the site is not protected very well if you’re going to put it in a holster. Also, when you’re cleaning the 365 you have to be careful not to use anything that could scratch the lens when you’re cleaning the barrel and the firing pin area. Neither of these problems are dealbreaker in any sense. The price is very hight but the product is quality.
