You can buy them from HK. They sell the ones that go on the new guns like the Custom Combat or Combat and Competition. I have one on my Custom Combat and honestly, I don't like it. The front sight is wide and I don't like how they lined up the front fiber with the rear sight. I, and many others I know, shoot low with it when going fast.
The sight on my new 2011 Brazos Custom is very nice. Thin front sight and if you can see the dot you are on target. With the HK you can see the front dot above the rear sight and still be 8" low at 20 yards. It's better to just get a tactical black sight since you have to look at the posts and make sure they are level and not at the fiber sight.
