I wouldn't use one myself in a fight, but I don't deny how useful the things are. I'll mount as many to my automata as I like, certainly, big ones and small, provided I can get enough ammunition and gunpowder for them. That's the drawback, of course. A sword or a spear can work as long as you'd like. A gun is a bit useless after a while if you've nothing to load it with.

[The solution to this, of course, is to have a lot of guns. He's learned from Sayaka's example on that one.]

I'd work on a way to fix that, but they're a bit small for me to be too interested in.
