Steel case is known to cause a little more fouling than most brass case ammo. My biggest concern with steel case is not the case but the fact that a lot of it has bi-metal jacketed bullets. Usually that translates to steel jacket meaning it can potentially wear your firearms barrel faster that copper jacket ammo if you shoot large amounts of it. YMMV
I use steel case in my SKS and AK's with no issues.
A little searching online and you can purchase brass cased for almost the same as steel cased. Stock up now, the stupid could start at any moment.
I'm a huge fan of steel cased ammo, although for rifle calibers and simply because of the price point.
For 9mm, you can buy re-manufactured brass cased ammo for $20 more than a case of Tula. While Tula, IMO, is perfect for plinking and training drills because it allows you more time on the range at a lower cost. For the life of me, I can't recommend it over something like Freedom Munitions brass cased. Simply because you can save the brass and use it for reloading down the road or turn around and sell it and put that money towards more ammo. Nobody is going to buy steel cases, but 1,000 pieces of 9mm brass can easily get you the $20 difference that you paid for that brass.
As for the "dangers" to your firearm, if it cycles, it will be fine.
The one area (aside from the aforementioned bi-metal bullet possibly causing premature bore wear over time) that I've heard of steel cased possibly causing damage is if shooting long enough strings that the gun gets hot and the polymer or lacquer coating on the case melts and makes extraction tough enough that it either fails to extract or snaps the extractor.
Dunno how common this is, but I've read accounts from a few folks who say it happened to them.
Naturally, I wouldn't trust steel cased -- even with proper expanding bullets, were it available loaded that way -- for anything more serious than range use, namely hunting or self-defense.
For either of those applications, reliability and accuracy are paramount, so be sure that your gun is sighted in for the brass cased ammo that works best for either use.
This ^. I have watched guys with a long cleaning rod and a hammer that had to pound a stuck steel case out of their ARs so, yes I have seen it happen.The one area (aside from the aforementioned bi-metal bullet possibly causing premature bore wear over time) that I've heard of steel cased possibly causing damage is if shooting long enough strings that the gun gets hot and the polymer or lacquer coating on the case melts and makes extraction tough enough that it either fails to extract or snaps the extractor.

I love the old, "that coating is melting and gluing rounds to my chamber and breaking extractor's" belief... the fact of the matter is that it's just not true. Ha! Jonny just beat me to it, but yeah, some people just don't want to admit that they can't properly maintain a firearm, or that they bought a piece of ****.

Okay, read the part about the coating not being the cause of extraction problems, but there were still problems with steel vs. brass, probably related to the steel not sealing the breech as well and allowing more fouling to go rearward, but that's just an educated guess, naturally:
Which Ammo Was Most Reliable?
The data which will probably be most interesting to everyone who reads this article is how often each rifle malfunctioned. To satisfy that particular thirst, here are the basic results:
- Federal: 10,000 rounds, 0 malfunctions.
- Brown Bear: 10,000 rounds, 9 malfunctions (5 stuck cases, 1 magazine-related failure to feed, 3 failures to fully cycle)
- Wolf: 10,000 rounds, 15 malfunctions (stuck cases)
- Tula: DNF (6,000 rounds in alternate carbine, 3 malfunctions)
