Just going to make a quick guide for anyone playing Gunslingers/Outlaws/Corsairs after Big Bang.
Long intro, etc.
Training spots:
Just train wherever monsters have the same level as you. Those are usually the only places worth training at, but at the end of the SP guide I'll post where I trained.
AP guide:
Generally you want your TOTAL STR to equal your level in order to equip gear. Therefore, a level 60 gun needs 60 STR. The rest of your stats should be in DEX.
I recommend the MOST you put into STR is 80, as a Zakum Helmet and other STR gear is relatively easy to get by 120. Personally I'm capping at 30 with a +1 Horntail Necklace as well as a bunch of other gear.
Remember to include potentials in calculating STR caps!
SP guide:
This isn't going to be level by level, as that takes too long and Gunslingers don't require anything fancy. It's all "max this, max that", so here goes!

Where I trained until now;
1~10 - Maple Island
11~22 - Blue Ribbon Pigs
23~30 - Mixed Golems
30~37 - Mushroom Kingdom Quests/Spear Pepe
37~43 - Upper Level Kerning City Square monsters (Mannequins, CDs)
44~70 - Truckers. Except they got nerfed, so go find somewhere else to train.
70~75 - Twisted Jesters. It was horrible, don't go there early on, I recommend the next spot;
75~83 - Monsters in Leben Mine. That's in Edelstein, btw.
83~88 - Iron Mutae (Magatia)
88~95 - C-2 (Magatia)
95~99 - Sage Cats (Mu Lung)
99~112 - Kru/Captains (Herb Town)
112~114 - Death Teddies
114~121 - Dual Ghost Pirates <You can start soloing Papulatus at 121 assuming you have Cannon and RF at that point>
121~125 - Gigantic Spirit Vikings
125~127 - Grim Phantom Watch, Gigantic Spirit Vikings
127~128 - Blue Dragon Turtles
128~130 - Red Dragon Turtles
130~132 - Pap solos (took a week or so)
132~135 - Brextons
135+ - Lionheart Castle!
Ignore pretty much everything from 120~135 after Lionheart Castle. You should really be headed there with a full party.
