Here's an idea for that. Make the knife blade rotate ninety degrees when folded, so it's sandwiched between the handles. That way, you've got the both handles to put the gun in. Another idea is superposed loading for the gun, which means that the rounds are end-to-end in the barrel, ready to be fired sequentially. To reload, you swap out the barrel itself. You could even have one in each handle, so it's two guns. The blade lies flat under the barrel when you fire it.
