I like Trijicon's as well. I now have two 228's (one of which is on the way to me) and both have factory SIG night sights, which are dead being KD's. Trijicon made them back then for Sig and I'm going to send both back to Trijicon for relamping. Cost is $57.00 per slide and you can pick green, yellow, or orange for the rear. Trying to keep mine factory but I'd consider the HD's if that weren't the case.
