You're not ready to care about your optic yet.
I keep seeing threads about footprint debates and dot size before the person asking can produce a consistent draw. That's backwards.
Your sight picture means nothing if your presentation is loose. Your dot choice means nothing if you're still chasing your grip every rep. These are variables *after* fundamentals, not before them.
If your draw stroke isn't repeatable—same depth, same angle, same speed—then optics talk is just gear shopping with a gun problem hiding underneath. Add a red dot to sloppy fundamentals and you've just made your mistakes faster.
Five thousand reps of the same draw. Same gun, same holster, dry fire only. When your presentation is automatic enough that you're not thinking about it, when your sight alignment is there *before* you're conscious of looking, then you've earned the right to evaluate whether a dot makes sense for you.
Until then, iron sights will expose every flaw in your stroke. That's the feature, not the limitation.
