Here is an image of three different pistols, all with night sights.
The three dots on the left are the sights on an M&P 40. This pistol came with factory night sights.
The central two dots are the rear sights of a P7M8 which had Trijicon tubes inserted earlier this year
The three dots on the right side are Meprolights mounted on a G-37.
Hope you find this useful.
