I've come from the old school of shotgunning where you did your gunning from a fixed choke barrel or you had a poly choke on the end of the barrel. In either case I've never had a problem shooting foster slugs out of either type of shotgun. Within the last three years I have either won or purchased 4 different, more modern shotguns and all of them have the screw in choke. The question I have for all of you is, is it safe to fire foster slugs out of any barrel with a screw in choke. My Mossberg shotguns do not recommend doing so and I was just wondering if that was so they could sell more barrels or is it a legitimate safety concern?
Firing slugs from guns with screw in chokes?

Yes, it is safe on any gun except for certain models of Mossberg with the "Over-Bored" barrel.
That barrel is closer to 10 ga dimensions, and gas blow-by with a slug could be excessive.
I'm not so sure there is any safety concern, but it is unlikely accuracy would be top notch with a 12 ga slug rattling down a 10 ga bore.
It is safe with any screw-in choke system, with any degree of choke except Extra-Full turkey chokes.

Foster slugs are not comparable in any way, shape, or form to steel shot choke damage.
The soft lead, hollow Forster slug is under full choke size starting out, expands to fill the bore, then swages back down to whatever it needs to be to go through the choke in question without damaging it.
They have been in constant use since they entered the market in the mid-30's in old full choke guns with very thin muzzles.
With no damage to them.
A steel shot charge is not compressible in the slightest.
Once it sets back in the wad to fill the bore, it tends to want to stay that way.

Well, I rather recently had a new Benelli M1 & also a Browning A-5 Japenese barrel with the full choke tubes marked "Not for Steel Shot". It has nothing to do with the threads, as all Rem-Chokes have always been the same thread.
The reason is as I mentioned in post #4.
A steel shot column cannot compress easily like lead shot or lead slug when it gets to the choke constriction.

That choke tube is a full choke. II RC steel shot is not recommended to be fired through a screw in full choke. I have seen some tubes marked steel full but I think they are more like a light modified but I have never measured one.
