How does a squib cycle the slide and chamber the next round?

Good point - you should be looking at a jam there.
Others have said it’s possible, though -

let’s get others’ comments on it.

If it is well and truly stuck, the back pressure can be enough to cycle the slide.

But it sounds funny. I have had a squib with a .38 Super and it did cycle although it did not close completely.

I hated the original barrel on that thing - it was an abomination and caused all sorts of problems - it headspaced on just a portion of the rim and 3/4 of the rear of the shell was unsupported. Got accuracy problems, bulgy shells, failures to feed, and the aforementioned squib.

Got a Bar-Sto aftermarket barrel that headspaces on the case mouth like it's supposed to, and had no more problems.
