Shawn, yes Sir. This shotgun comes with a 3-Piece Choke Tube Set Improved Cylinder, Modified and Full. Foster Type Lead Slugs are fine in any choke but accuracy results are much better using Improved Cylinder Choke as there is less swaging (deformation) on the slug so it will have better flight stability.

Shawn, standard lead slugs is safe in a smoothbore shotgun, just do not use sabot slugs.

3 chamber can handle a wide variety of 3" and 2-3/4 loads and yes including slugs.
