No interest in solutions which preclude iron use - especially those that preclude irons even with the optic removed.
The one I posted is at least interesting.
As I mentioned, the Magwedge has a groove down the middle that serves as a rear sight in a pinch. You can probably add a low profile rear sight that will work with the front sight, if so desired. HTA makes a low mount picatinny sight that uses Glock sights. It *may* work, haven't tested it. The U notch is sufficient enough for me. Both give you a much longer sight radius as compared to the stock sight. And honestly, if you can't get the job done with either, I don't know what to tell ya.
I also mounted a 45 degree adapter and installed a SeeAll Tritium Micro Rail Sight. Weighs nothing, no batteries, and gives me a quick CQB option. So now I have PA 1x micro prism (etched reticle, so batteries die, it still works), usable rear sight rail, and CQB offset sight. I think I have all my bases covered. Will know for sure once I get it out to the range and test the new PA prism sight.
Honestly, the VZ doesn't need any of that, but I like to tinker. I've been using mine in two and three gun competitions for years. Sometimes it was with irons only, other times it was with a RDS mounted to a Bonesteel upper handguard rail. Easily hit targets out to 300 yds.
