Seeall mk3 - SeeAll Open Sights MK3 Tritium Pistol Sight Plate System

Works great! This product works just like iron sights but better and doesnt use batteries so it has an advantage over red dots with not dying. If you dont want to be bothered with changing batteries on a red dot and are worried with them dying this is a good option. Also is tritium lit so it glows slightly in dark environments. Only down side is its not as quick lining uo your shot as a red dot will be.
