Tino_Please remember that the pistol is so RNG that if you hit more then 30% of shots on average you are a god. 30% pistol is what quad hit, and he is seen as the best pistol scout in the history of the game by many. You will not be hitting those numbers in any realistic game or scenario. That being said it is probably better then stock and on par with winger. Id say combo scouts run winger because you already have heals, and flank can run PBPP because the chance for that burst HP can turn a flank fight to your favor.
Over the course of a 30 minute game, sure, but those numbers are enormously significant during action. Hitting just 4 shots gives you 28 (slightly more than a small pack!) let alone the full 63 one clip can give you. Literally everyone has had that one magic clip where you just hit all 12 shots. Huge bonus in still being able to heal while doing decent damage? I can think of a million different scenarios where the new pocket pistol saves the day. This is pretty much a straight upgrade to stock.
also yes there's rng to it, and this makes the rng of the pistol extremely important and shouldnt exist
