Yes this will shoot slugs, it includes 3 chokes (improved Cylindet, modified, and full) the improved cylinder choke is going to be the best to use with slugs in this shotgun. "Improved Cylinder – This type has the least constrictions. You’ll find it recommended in most Foster Slug ammo boxes."

it can shoot any 12 ga slug foster (rifled) type slugs work best with the smoothbore barrel and while IC or cylinder chokes usually give the best pattern dont be afraid to try the mod choke. The sabot slugs will give great accuraccy with the addition of a Rifled choke tube like this choke-tube.com/proddetail.asp?prod=19474

Ryan, since this is a smoothbore barrel, you will want to shoot foster (or rifled) slugs, and you'll get best results with IC choke tube installed. Have a great day!

Ryan, slugs are no problem. Foster Type Slugs such as (budsgunshop.com/product_info.php/products_id/411559534/rio+royal+star+slug+12+ga+2-34+1oz+slug+5rds) are recommended and you will get the best performance/accuracy from the Improved Cylinder Choke as there is less deforming forces on the slug during exit through the choke. Cheers and stay safe!
