A sight pusher is recomended to install these but The Trijicon night sights are better than the Sig OEM more contrast in moderate light and sharper in low/ no light. You will need professional installation or a sight pusher to install without causing damage, but these were just right for the 229
Pros: Accurate, Bright, High Contrast during daylight
Cons: Special tools needed to install properly
