spotted a post about firearms damage in D&D, and here's the thing; being shot is deadly. You could say the same for being hit with a bec de corbin, stabbed with a humble dagger, or bitten or swatted by an array of fantasy critters which make hippo or shark bites look minor, BUT

Hit points in old-skool D&D aren't just physical toughness; they're about luck and fatigue as well as blood loss and shock. Which only *sort of* justifies how mighty heroes should be able to keep going.

I feel like you can either go two routes with this; firearms damage is like all of these other terrible threats, stuff which can put an adventurer in a shallow grave - or another variety of hazard which an unrealistic over the top hero can survive. This gets back into how I've been feeling like my alternatives to D&D are either Dungeon World or Pathfinder 2e.
