In context... The vast majority of civilian defense shootings(high 90's percentile) take place inside 3-5 yards. Sights are irrelevant inside 5 yards for likely scenarios IMO.Therefore, sights are pretty much irrelevant for civilian defensive shooting. Prioritize your training accordingly.

"For close range gunfighting inside of 5 yards, any sights are irrelevant. You explode off the line of fire, press the pistol to the threat and press a burst into their chest. You wait for nothing and use physical indexing methods."
-Gabe Suarez

So, will you and should you focus on your front sight or focus on the threat inside 5-7 yards in probable and realistic civilian self-defense scenarios?
