Both are good options. Personally, I would go for Trijicon HD's. You may also want to consider just doing a front night sight and a plain black rear sight. I have my Glock 19 set up that way and really like it. Having said that, I've also got Sig factory night sights, Meprolight night sights, Trijicon, 10-8 (which I believe are re-branded Trijicons), Ameriglow, and Truglo. All are perfectly serviceable and do their job well. Currently, I'm very much partial to the factory night sights that my Sig Legion pistols have, however.
