Definately the Night sights. I prefer Trijicon over Meprolight sights, but that is just me. See if you can find both at a local shop and se which ones you like better. I use Trijicon sights on both my 1911 and my XD40, as well as a trijicon reflexII on my SAR1. I have beaten the hell out of my SAR1 and my 1911, and neither sighting system has failed yet.
