According to the tooltip the sniper trait gives an aiming bonus for everything except pistols

I've noticed with these settings that when firing long auto bursts the first few shots will miss, then a couple hits, then misses...it seems to simulate raking a target with autofire very well (before these settings I found that auto bursts tended to either have one bullet hit, every bullet hit, or no bullets hit).
