I would like to use the gladiator and gunfighter pro in a dual setup.
Will a left hand grip become available in the future or is it possible to modify the gladiator as of right now for left hand use?

There will be a left-hand grip coming that will fit the Gunfighter/Gunfighter Pro/Gladiator Pro/Gladiator Pro Mk.II; however, don't expect that to be available until Q3 of 2017.

The regular, non-Pro Gladiator will not have a left-hand option, as its grip cannot be swapped out with replacement ones.

EDIT: Just to be sure, I will ask VKB HQ and see what they say.
