Retention hood doesn't work with all after market sights - Galco Parabellum Shoulder System, Leather

I just got this rig today. It seems nice, not sure what the other reviewer is talking about that it's cheap. Maybe he was expecting something heavier and thicker, lol? I don't agree, seems high quality but time will tell.

I wanted something I could wear when riding motorcycle, running to the store and not wearing pants with a belt. After I've actually used the rig for awhile I will update the review. So far I can tell you 3 things:

1. Assembling and adjusting the rig wasn't hard
2. The retention of a loaded G19 without the "retention hood" down (so the internal part that "snaps" onto the trigger guard inside the holster) seems very good. I was unable to shake the pistol out of the holster. Possibly it will weaken over time? That remains to be seen.
3. I have Trijicon HD night sites on my G26, which are very popular and common. The sight height is pretty much the same, but these sights are about 1/4" farther back on the slide, which is enough to interfere with the function of the retention hood. I can flip it down, but require 2 hands to open it, cannot do it quickly with thumb as designed and this just won't do.

It would have been nice to have a warning about this in the product description. In my case, I doubt I would need the hood if carrying the G26 if I wanted to, but I also can't imagine carrying the smaller Glock with this holster. My G19 still has stock sights and the hood works as described. If I decide to upgrade to non-stock sights, will have to take this into account.
