Not all shotguns use removable choke tubes, but all shotguns have some
degree of choke, ranging from "none" (cylinder bore) to "a lot"--the above
mentioned extra full/turkey choke.
If your gun is threaded for screw in chokes and you don't have one screwed in, you might
want to get a choke tube and screw it in--just to protect the threads.
If your gun doesn't use screw in chokes, look on the barrel. Typically left
side, just in front of the receiver. Does it say Full. Mod., Modified, I.C,
Cyl,. anything along those lines? If you have a 870 Express with fixed
choke, it's probably Full or Modified. Slugs are fine in either.
