Typical "my weapon is nerfed" discussion. I usually play agility and feel the pistol is underpowered. When I played strength last time I ran around on ground level on horde night because the shotgun was so powerful.
With a pistol I really need to do headshots all the time, even with low-level zombies. I can put a whole magazine into a zombies body and he might still stand. Shotgun? Just point in the general direction and shoot, guaranteed hit and kill with two shots. Disadvantage is you need two double-barrels in your toolbelt (as long as you don't have a combat shotgun) and yes, low range (but that is adjustable with mods, try that with the club

)
