The holster was designed for use of red dot sights also. It helps “cradle” the sight a little. If a person didn’t want it, it could be not included in the build. The picture is just a prototype. I’m wearing it everyday to see what hang ups it might have. So far so good. The portion your inquiring about, I’ve also found helps as a guide in reholstering. But, once again, it’ll be a preference. Thank you for your question though.
