Tedtacular bearington does, and dragon familiar.

Quite a few, but then again, not as many as you'd probably think. I just made no sense...
Anyways, it'd be better to give a theme or color scheme.

if you care, most nx covers will end up on the inside hand (as it should, that was where your gun was)
but if you want the weapon to end up on your outer hand, the Shockwave weapon does that. and also any other "energy ball" kind of weapon i assume..

The spring blossoms cover a gun, im not sure what else does. Maybe a dragon familiar?
