1-4 Bleed Stacks on non-Weak Spot Hits.
12.5-20% Critical Chance for 6s on successful Dodge.
30-60% Rending on Critical Hit.
4.5-6% Critical Chance for each expended round in your weapon (resets on reload).
Note: the perks on both weapons are the ones I'm actually using but they're probably not ideal. If I could freely select (break the locks!), I would probably take:
Knife: +25% maniacs / +2 stamina
Revolver: +25% carapace / +25% flak
Hand-Cannon is a good blessing for the new revolver. However the old standby of Surgical doesn't work well for the fanned shooting playstyle. Crucian Roulette seems to work reasonably well. I can also imagine Sustained Fire or Point Blank being effective, depending on your playstyle. Trickshooter could be amazing if your aim is very very dialed in (sadly, mine isn't).
