Perla Pistol Skin bugged when equipped with a Glaive

[Aturixios]

When dual-wielding a Glaive weapon, the Perla Pistol skin doesn't change the pistol's appearance to the Perla's shape, but instead just pastes the skin onto the selected pistol. I've made a small album of examples. In this album I've only included using the normal Glaive with Kohmak, Hystrix and Euphona Prime. But it also goes for using Falcor as the glaive, and any other pistol for the pistol slot.

Perla Pistol Skin with Glaive

The colour scheming doesn't seem to have a problem when I try change the Perla Pistol skin's colours, but it's still a bug that should be addressed.
