My holstering ritual involves mag and press check, visual inspection of the holster, then the weapon. It's pretty useless empty. But if I ever fail to load it, there's two spare mags on my weak side. I fail with that, I'm perhaps mentally incompetent to be carrying.
Deliberate actions are part of developing successful habits.
