Howdy, everyone! This is my first post on the Giant in the Playground forums, and I must first say the The Gunslinger's Handbook has been indispensable in creating my first Pathfinder character.

As this is the first time everyone in my gaming group will be playing Pathfinder, I gravitated to the Mysterious Stranger at first glance. I even set it up with the GM to purposely arrive late to the first session, arriving on the scene murdering what appears to be a friendly NPC to cause a ruckus and get the story moving.

In any case, I'm building the character to be a darkly charming Half-Elf, fewest-shots-to-kill-with-a-single-pistol kind of guy. Since this is my first foray into Pathfinder (and really, 3.5-3.75 in general..), I'd really appreciate build advice if y'all would be willing to offer it. I'm mainly concerned with feats right now, planned out like this:

L1 - Rapid Reload (Pistol)
L3 - Point-Blank Shot
G4 - Rapid Shot
L5 - Deadly Aim
L7 - Precise Shot
G8 - Weapon Focus (Pistol)
L9 - Dodge
L11 - Mobility
G12 - Deft Shootist Deed
L13 - Snap Shot
L15 - Improved Snap Shot
G16 - Combat Reflexes
L17 - Improved Critical (Pistol)
L19 - Critical Focus
G20 - Impact Critical Shot


TL;DR - Thoughts on a Half-Elf Mysterious Stranger, specifically feat planning?

I would greatly appreciate any input offered.
