I am getting the opportunity to get a Browing BPS Stalker 3" or Hunter 3" through a rewards program at my wifes work


she is sharing, what a great wife. From doing some searching on the site it looks like they are highly regarded guns. I just want to make sure it will take care of me for the hunting that I will be doing: dove, turkey, waterfowl, deer, pig. I should not have a problem putting slugs through it right?
I can get the Stalker in 26" or Hunter in 26" and 28". Why the difference in barrel lengh and what benefits does it offer.
It comes with the Full, Modified, and Improved Cylinder chokes, are there more availble? i.e. turkey choke
I am leaning towards the Hunter, that walnut looks really nice.
I know it is a lot of questions, but thanks for taking the time to read and respond.
