But putting the blade in the barrel screws with the aim of the gun, and is a solid flat surface on one half on the barrel which messes with the bullets trajectory. That's my point; it really can't retract into the barrel because it screws with the gun function too much. We even have examples of guns where that sort of thing would make sense, but they didn't do that.

Nadir's rifle, Gambol Shroud. Reese's hover board has the blades under the barrel instead of part of it. Even Pyrrha's gun, Milo, has the blades actually flip and fold down to become the stock of the gun, and the barrel is in the grip, in front of where she keeps the ammo for her rifle.
