Start doing some skeet shooting so that you know how to use that hunting shotgun. You may need it for birds and small game.
The chokes narrow the pattern. Essentially, if you are shooting game further away (over app. 20 yards or so), you want a tighter choke, especially for larger game like deer. If you are shooting game that is closer (under 20 yards), you want an open choke as the tight pattern will tear all the meat to shreds and ruin the game.
Your self-defense version probably has a fixed choke. You could use it for hunting in a pinch, but it is not optimal.
I think I will put the 28” barrel on and do some target practice with it. I’d like to see what my accuracy with rifled slugs will be.
Skeet is a good suggestion. Not sure of the practicality since I shoot on private property, often by myself.
