SD situations occur in such close distances usually point shooting is the way it goes down, so no laser/RMR/dots will change/help that out. So, practice brandishing your edc at 10 & less yards, and point shoot till you are in the COM with your first shots. If you gotta be a pistol sniper and make headshots at 25 yards, then by all means, strap a big heavy sight on yer pistol, hire a caravan to tote it and get er done however you see fit.
