...That's fairly difficult. I planned to use the hilt as the main way to transform the weapon, but based on it's design, it looks a bit tough to work out.

Alternately, you can make the blades foldable, but I feel that looks too much like Gambol Shroud.

Mid-type Addendum: The designs seem to work well. You just need to modify the blade's lower part to be larger and sligtly thicker to accomodate the transformation sequence and the gun mechanics.

...I'm pulling technobabble outta my ass. >_>
