One of the reasons I love teaching instructor classes is I get to spend time with very knowledgeable professionals and share knowledge with them. I generally learn as much from them as they learn from me. This Glock Rear Sight Tip is an example of this.
In one my Pistol Instructor Class, I noticed one of my students had marked a small dot in the middle of their Glock rear sight.
We discussed what he did and why, and I spent some time playing with it. I felt it was something useful to share.
Especially relevant to the conversation, if you are in Northern Mississippi and are looking for a very smart firearm instructor, let me know and I will pass you info on to him.
Anyway, take a fine tipped sharpie and place a focus point on it. It can be a line, dot, or diamond in the exact center of white line in the glock rear sight. Probably a dot is easiest. As a result, this point can help those of use with older eyes line up the front and rear sight.
The only caveat is that you need to ensure it is exactly centered on the rear sight.
In conclusion, I want you to try this Rear Sight Tip, and tell me what you think.
Finally, to address comments from my original youtube video. As a result of trying to hold the camera and the gun, my sight alignment was off.
