Just a heads up for folks on a really good way to approach HK luminescent sights. I know a lot of guys don't like them, because you need to charge them.
The trick is all in how you charge them. The best method is a good UV light source. I used this guy:

A 20 second charge with this UV light charged the sights enough so that after an hour they are still glowing, with about 75% of the intensity of my tritium sights that are a few years old.
Charging with a strong white light flashlight seems to fade about twice as fast.
