Hello,
    I just purchased a new (used) Gen3 Glock 19. I brought it home to clean; had a dirty barrel. I ran a soaked patch through it and  let it set for about 15 min. After I ran a dry patch to see how much scrubbing I would have to do and to my surprise, the barrel was shiny and like a mirror. Something I saw looked puzzling. The rifling seemed shallow. Is that the way it is with the polygonal rifling? That is why it is not recommended to use lead bullets if reloading for a glock? Thanks.

Polygonal rifling looks like that, yes.
Also, I never scrub my barrels on...well, any of my guns. Maybe it's cause I clean after every outing, but I only run patches and the bore is mirror shiny. I seriously can't imagine how much shooting it must take in between cleanings to need to scrub a barrel with a brass brush like some people do.

Polygonal rifling looks shallow because there aren't any lands sticking up as in traditional rifling.  What you are seeing are the edges created by the adjoining surfaces.

Yep, the barrels don't need that much attention.  I have about 6000 rounds through my 34 now and I think I've actually only put a brush down the barrel two different times.

You really don't need to clean your barrels that often.

Maybe every 2000 rounds.

I don't think I would ever scrub a glock barrel with a wire brush. I run the occasional boresnake through it.

Brass brushes are fine in barrels.

Especially Glock barrels, no problem.

Boresnake for me, too. I run one through after every range session. A few passed and it looks clean and bright and shiny. I still field strip to clean around the ramp and such. I know Glocks can go a long time between maintenance, but I clean and lube after every range session anyway.

I have my favorite 19 right now, and I am punishing it.  I've got about 3K thru it, and all I have done, is wipe it down, and shoot it.  Ya wanna know what it does????   Goes bang every time.  I can't speak for all other guns, but I can assure you that the 6 Glocks I have can take a pounding.  Fret not OP, shoot your new gun, and enjoy it!

As others have said- you are fine.

Pretty much the Glock creed. Just go shoot it.

As a Glock armorer I would advise you to use only a very light lube as advised in the owners manual with whatever firearms oil you have handy.

Excess lube will get your gun all gummed up and cause some function issues , no oil at all will in theory cause some excess wear but I honestly have not ever seen that .

Pretty much any Glock problem I have ever seen was somebody takeing their gun apart past field stripping and not putting it together correctly or over lubeing it .

Lead bullets can cause kabooms with Glocks, because of the way the bullet picks up the rifling.

Lead bullets cause problems in a few ways:
1) some dope puts a pile of lead through his gun without incident the. Stupidly shoots a jacketed bullet through the constricted bore "to push the lead out" boom
2) some dope uses an over charged reload
3) some dope has an undercharge squib then tries to fire another bullet behind it
Obviously number 2&3 can happen with jacketed bullets as well.
I myself have and no many others that put tens of thousands of lead rounds through glocks no problem:
Key points:
1) cast bullet not swaged
2) reload within specifications - never load hot just enough to work the action is all you need
3) clean your bore with a brass brush every 200 rounds or so - a few passes of the brush under a minutes work does the tric
4) never try to shoot a jacketed bullet out of a bore without cleaning the lead fouling out first
