Valente, the Escort shotgun is shipped with a 2-round magazine plug. If you unscrew the magazine cap, you can easily
remove the plug, thereby enabling you
to insert 5-rounds into the magazine.
You need to keep the plug, as the
hunting of some species requires a
Maximum loading of 3-rounds. Enjoy
your gun!

Velente, the gun is shipped with a magazine plug, you need to unscrew the magazine cap and remove it.

Valerie, just unscrew the magazine cap and remove the dowel pin that limits the tube to 3 rounds and replace the cap. Cheers and stay safe! Same directions as this video : youtube.com/watch?v=lAWJERcI2wM

Maybe there's a mag block to limit capacity to 3 rounds for hunting. If there is it'd be removable. If you've already checked that id contact Escort and see what they say
