what's the phonetic spelling of the sound of a shotgun pump?

but srsly folks, it's not even being pro gun, in a way. to me that's sort of like being "pro-rake". I need a rake for leaves and I need a gun for ... other purposes. I mean, I don't feel a need for it, even, like I can't sleep without one. Likewise I could just let the leaves rot or mow over them and let them mulch in place. This analogy is breaking down.

Point is, I don't have to be pro-gun (I am) or anti-gun, in any larger or symbolic sense. But I do greatly feel a sense of duty to the whole picture.
