I do not know if this bug is exclusive to guns. They are the only weapons I've been able to test for this issue. Testing on other weapons with a reload- + attack-speed of less than 3 sec would be desireable.
1a. Load the attacher savegame.
1b. Create a Ranger with max dex and proficiency in pistols. Level him up enough to aquire the gunnery passive. Aquire 3 pistols, and equip 2 in one set and 1 in the other.
2. Enter combat with the 2 preloaded pistol set activated.
3. Fire the initial salvo with a total combined attack-speed of 1,3 sec (in my save, I'll be defaulting to my saved numbers from her on), and observe it working in approximated accordance with tool-tips.
4. Activate the pistol-modal for a combined attack-speed of 2,5 sec. Observe it fireing at a frequency of ~3,5 sec, not in accordance with tool-tips.
5. Switch to single pistol and activate the pistol-modal, for a combined attack-speed of 2,8 sec. Observe it fireing at a frequency of ~3,5 sec, not in accordance with tool-tips.
I've made a thread for an attempt to gather information on what weapons or means of attack are affected by the bug:
Weapons/Attack-types known to be affected:
Blunderbuss (from Zzz)
Weapons/Attack-types known to not be affected:
