Purchased based on price and limited positive comments for my M&P 9 C.O.R.E. that I carry concealed. Mounted easily using #5 mount plate that came with pistol. Zeroed easily. 8 MOA dot worked well in auto mode. Sight turns off after several hours. Can not find this feature mentioned in description. Perhaps this is a malfunction? Obviously unacceptable for a defensive handgun. I can recommend it for general range or hunting use.
Pros: Price and range or hunting
Cons: not for defensive weapon
