In guns with a thinner barrel wall, you will often find that the barrel is bulged behind the squib, Ruger's barrels are built absurdly thick, and from what I could see in the photos, I'm not seeing an obvious bulging. But that's from examining the photos - if I had the piece here in front of me, I'd be making measurements with a mic on the outside of the barrel, and running a snug patch down the barrel to get an idea whether it is bulged or not - not depending on visual inspection alone.
Shotguns can squib too - Sometimes, the plastic wad is left in the barrel after a shot - the shot went downrange, but the wad/shot cup hung up in the barrel. In those cases, you'll see a very defined bulge in the barrel. Sometimes, a shotgun barrel splits open like a peeled banana. It's not pretty.
Here's an example in a flop-top revolver (ie, not a Ruger):
