Okay, hell. I didn't say make the elite pistol 1 handed. If I did, then Sniper's elite bow would have to be 1 handed as well to balance, right? And that would be rape. A 2 handed pistol is fine, GS players have got to learn to switch between shield and gun.
My point was, if classes like LK can have 1 and 2 handed Swords (Spear too right? Never saw the whole set), Sinx with Daggers and Katars, why can't a GS have a Pistol and Shotgun? I'd say Grenade Launcher, but Ground Drift being the only skill, it's not really worth it. Inferno and Destroyer do that skill justice. And don't get me started on Gatling Guns. But the Shotgun actually has useful skills.
