In the current state of meta there is almost no reason to have high initiative because almost always you can start combat manually from stealth or from cover and make your move first. Now I only have a small suggestion here, maybe someone can add something to this as well.
My suggestion would be to add a feat that gives firearm pistols a chance to incap, stun or daze a target in the first round of combat if your initiative roll was higher and this chance depends on the difference between your and your target's initiative roll.
That would synergize nicely with gunslinger, make trigger happy and paranoia viable and desirable pick for min-maxed characters and overall give gunslinger characters interesting gameplay choice of walking in enemy territory unstealthed and trying your luck with initiative rolls, chances to hit, chances to proc this feat and what it will do: stun, incapacitate or daze. Maybe add knee wound to this if your character has respective feat.
Maybe it would be OP in arena or overall, or still not preferable to stealth, anyway, just wanted to express this little thought of mine.
