Guess it wasn't meant to be. I returned the red dot as I couldn't hold it steady, was more accurate open sights, and put on Ameriglo CAP sights. They are awesome at 10 yds. I tried shooting at 25 yds and I couldn't see the target with my readers. I bought this G40 for hunting and there is zero chance of me qualifying with it at my club. Qualifying is 2 out of 3 bullets in a six inch circle at 50 yds. No sense in keeping a 10mm that I can only shoot a max of 10 yards with. Sucks beyond words. I guess pistol hunting is out for me. Another one to GunBroker.
