Garlean Gunblade Job?

[Jandor]

According to the lore provided by the starting Gunbreaker questline....

....they're just called "guns". It's also why they call the job "Gunbreaker", as their tactics were designed to fight specifically against Garlean weaponry.

If I recall correctly the Gunbreaker Gunblades were designed to fight against Allagan guns, some suitably ancient foe anyway.

Garlean gunblades in turn were inspired by Gunbreakers, with Radovan considering their weapons to be inferior imitations, while the Garleans obviously consider them to be superior to the original.
