You have got a turkey killing machine! I have this one, a Mossberg SA 20 Turkey Thug, and a Stoeger 3020 in the semi auto 20. This one will shoot with any of them and maybe pattern just a bit better than the others. I use a sun optics dove tail adapter and run a red dot. I have killed several Gobblers with this gun and it's never failed me! I use the Carlsons .575 non ported turkey tube and Federal #9 TSS. I think you were talking about the Mossberg SA 20. They both have chrome lined barrels the Tri star has a barrel that is 24 inches were as the Mossberg is 22. They both use the bereta / Benelli choke tubes. My point is very similar. I have not had one problem out of mine , it's a good gun! It's a Gobblers nightmare!
