The thing retracts the barrel due to weight distribution to balance the offset shape of the bow. The barrel acts as a weighted counterbalance like the ones used on some bows. Same thing for the mag. It can't offset the weight, otherwise you can't use it properly.

I could always add another button or trigger for transformation, but to be honest, I don't know how most of the show's weapons transform. They don't have a visual mechanism or gesture to activate. Ruby's scythe, Yang's gauntlets, Roman's cane, etc.
