Yeah, I just edited that in. I like the autopistol fine. Here's how I'd tier things after roughly a week of play:
S: Mastiff, Kraber
A: Peacekeeper, Triple Take, Wingman, Spitfire, Devotion (turbo)
B: Prowler (auto), G-7 Scout, R-301, Flatline, R-99, Devotion (regular)
C: Longbow, Hemlock, EVA-8, Prowler (burst)
D: RE-45, Alternator
F: P2020, Mozambique
But really I'd take any two from S/A/B here and be happy. There are a lot of good guns.
You still have to break shield, but headshots do double damage (1.5x times for shotguns and SMGs to mitigate the pellets).
