I did get my slide back from James @ XD/HS2000.com with new Trijicon HD's installed. Turn around time was one week and the install is perfect. Thanks James!
I've been so busy at work I have'nt time time to shoot it yet. But...
The Trijicon sights just look much better IMO. The rear sight extends to the rear edge of the slide giving you a 1/2" more sight radius. The TFO's do not extend to the rear. I've always disliked pistols & sights that are not mounted as far back as possible. Why give up sight radius when you don't have to? Also, the TFO's are just overly long looking( due to the fiber tubes, I get that).
This has a lot to do with who intalls them. Especially on an XD. But they fit perfect. The TFO's fit perfect as well.
For me the Trijicon HD sight picture is much better than the TFO's. The rear notch is larger which makes it very easy to center the bright orange front sight in the notch. Making for a fast flash sight picture. The rear sight is basically black in day light as the tritium tubes only make faint dots in day light. IMO no dots in the rear is better. The black rear sight really makes the orange front pop. The TFO sight picture is great if you like 3 dots. And they are very bright in daylight.
Night/darkness sight picture on the Trijicon's is good & great. The tritium glows very bright, front slightly brighter than the rear, but reverts to a 3 dot system. Though the bigger rear notch helps. BUT, if you hit the front sight with 2 or 3 seconds of bright tactical light the orange dot will glow strong for about 20 seconds. Bringing back that awesome daylight sight picture where it's easy & fast to center that front sight in the big rear notch. The glow starts to fade after 20 seconds or so. TFO night sight picture is pretty good. Mine were green front/yellow rear so picking up the green front sight was pretty quick in darkness. The TFO tritium had plenty of glow to it also, slight dimmer in the rear as the yellows are not as bright as green.
Two other things I like about the Trijicons. The rear sight forward edge is vertical and slightly angled forward making it perfect for an emergency slide rack on cover, your belt or holster or whatever you can get too. This will be helpful if your other hand is not usable for any reason. The TFO's pretty much are useless in that regard because they are ramped & have only a very short forward edge.
Last the Trijicon rear sight back face is angled back slightly and serrated. That'll reduce chances of any kind of glare on the rear sight. TFO's have no real rear sight face due to the way they are made. Though I didn't ver have a glare problem with them.
Bottom line, for a defense/combat sight on a defensive carry pistol the Trijicon HD's are my top choice. I will install Triji HD's on my wife's pistol and any other pistol that I use. I think these would be great for competition too. Which I hope to try soon
Phone pictures are not great but...
