red dot for beginners!! Hi all, I have a question about red dots and zeroing them. I have been collecting firearms since I was 18!! I have a really nice collection and my problem is that none of them have a red dot on them! I recently bought a sig p365x with a holosun 407k-x2 and I really don't know how to zero it correctly! I was wondering if my fellow members from sig talk could help me out.. I'm not sure if I have to co witness the dot with the front sight or should I have the dot in the middle of my dot window?? I read of both ways of doing it but i'm not sure which is the best way of doing it and the easyest way of zeroing my red dot!! If I could get some direction on the correct way of zeroing my red dot I would greatly appreciate it!!! THANK YOU VERY MUCH
