My first exposure to self-loading centerfire pistols was when I got a Government temp job in a Peace Keeping mission: I was issued a Sig P226 to carry, in addition to the assault rifle. We had to carry with empty chamber, so I picked the surest and fastest way to rack the slide, minimizing the need for fine motor skills: grab the slide from above, at belly level, with thumb and index finger on rear serrations - push gun through and meanwhile maybe pull back on the slide. Haven't felt a need to break that habit.
I'm more gentle when handling an empty gun.
