Applying Youtube Knowledge from @GBRSGroup

After a customer asked about not using sights or optics. I expanded on this subject a little more from a previous video at the range with a CZ P10C. I did not come up with this myself I remembered seeing DJ Shipley talk about this in a @GBRSGroup video a while back and also a little bit in a shorts video. I also wanted to cover seeing a video with knowledge such as this and not using is actually just knowledge lost. I hope I got it correct enough to convey the purpose.
