Hi Joseph, yes sir, this will fire both 410 slugs and buckshot. It comes with 3 choke tubes, full, modified, & improved cylinder.
Do not shoot slugs through a full choke. Improved cylinder will give best results with slugs.
Stay safe & have a great day!

Yes, slugs and buckshot.

I think Randy I. posted this answer meant for maybe another question?
Anyway, yes, you can shoot both .410 slugs & Buchshot.

NO IT IS UNSAFE TO SHOOT A 45LC in a 410 look at it this way the 410 has a bore diameter of 0.41 inch the 45LC uses a 0.454 bullet trying to push a .454 bullet through a .410 hole will cause a huge spike in pressure which the gun is not made to handle. Guns like the judge can fire a 410 because the bore is made for a 45LC which is larger than 410.

Hi Joseph and welcome. Yes Sir it can. Slugs through the Cylinder and or Modified chokes only, never through Full Choke and buckshot can be shot through all 3 chokes with modified or full producing the better patterns. Cheers, stay safe and enjoy!

Good afternoon to you!! The Citadel Levtac-92 can handle both slug's and buckshot. The Levtac-92 come standard with 3 choke tubes. Have a good rest of your day.

Yes.
