Oh wait, did you make it fit into the shields slot?

Yeah, the thing is when you put it as a shield (as Charmless stated), it works in the BunkerBuilder Menu, but then in the order menu, it doesn't show up. So if you want to dual wield, you'll have to buy a bunch of stock and place it somewhere... Kinda sucks...

LAME!

Fix what? To be perfectly honest, this whole offhand thing was a huge hack to begin with. Up to this point, offhand weapons were never intended. Nothing was broken, because there was nothing there to break. You can't rely on hackish mod tricks to still work between builds.

If offhand weapons are ever intended, then probably the way it will work is that you just buy two one-hand weapons, neither of which are necessarily designated as "off-hand." Then if you had a lot you'd probably switch them off per-hand. Basically, this whole "buy a gun that's designated as an off-hand weapon" is nice and all, but realistically a handgun can be held in either hand, so you'd just switch one weapon.

So, until the nice folks making CC actually make a real dual-wielding system, people can't really complain about their little hacks being broken because of updates of the real game. Maybe the hacks are fun, but they aren't guaranteed, nor are they important in the face of real updates.

Ok you win...
