well, i beg to differ about the handgun efficiency for SS as it currently is setup. i never run out of 9mm or handcannon ammo when used alongside a crossbow. i also get plenty of kills adding extra "mop up" fire power just by using the 9mm alone. but that is exactly the problem! lol. i can understand the headshot damage bonus for SS applying to all weapons (so 9mm, handcannon, shotgun, crossbow, AK47 etc.... ok), but the damage bonus for handguns as a SS weapon is a bit, well, stupid. again never understood why in october that change was added because before then, this issue didn't exist.
the point is taking the handguns away from any particular class (in this case the SS), as they don't belong to those perks, and giving them their own rightful perk. as for the various ideas on abilities, tier3 weapon, to give to the gunslinger, how to level it etc...it's burried in pages of this thread.
