Thank you all for the advice and opinions! You've mentioned a few things that I'll look for when purchasing, like the removeable chokes and precision sights. I appreciate all the input on the gun, as well as hunting advice and the YouTube suggestion.
Some such as Mossberg 500 come drilled/tapped for a scope rail, so if you don't get a dedicated turkey gun (smoothbore barrel with rifle sights) something that allows you to mount a red dot would be another option.
