My weak side shoulder has some tears (actually both sides do), and when I was at A8 last year, unloaded start, something stopped working in the shoulder and I could do little with my left hand for slide racking. Zeroed that stage (Stage 7, I believe). Even now unloaded starts are a loser for me as I cannot grip and rip from the front of the slide like I can at make ready. Apparently at speed it's a no-go. So I've found myself grabbing the optic this season in the first 3 matches. Not consciously, just happened. Far less pain and better maneuverability with the hand. If the optic goes, it goes.
I'm not going to win anything, those days are gone, so better comfort than pooping the bed.
