It's hard to see the Pics on my phone but I think the "catch" you're looking at is your ejector. Again, It's tough to see on the phone. I could be wrong.
The part you are asking about--the little spring loaded hook on the slide--
is the EXTRACTOR. It hooks the rim of the chambered cartridge, and when
the slide moves rearward, either manually or as a result of the gun firing,
it extracts (pulls) the casing out of the chamber.
On the top of the frame in your picture with the slide off, there is a little
nub sticking up on the left side, just to the rear of the magazine well
opening. That's the EJECTOR. As the slide (with the casing held to it by
the extractor) moves rearward, the ejector hits the rim and ejects the
casing from the gun.
Most (but by no means all) guns, regardless of action type, have some
form of extractor and ejector.
Nice old model B. Feed it standard velocity ammo and it will still be
a functional family heirloom for your grandchildren. Hypervelocity ammo
and Mini-Mags are NOT the ammo for this one.
The recoil spring in the old High Standard fixed barrel guns can be a little tricky, and the guns can be ammo sensitive and require a little magazine
tuning---but they are and will continue to be crazy accurate and a pleasure
