I cant speak specifically about the choke for that gun. I use a 585 trulock in mine and it throws a fantastic pattern. Low 300 count in the 10" at 40 yards with 1 5/8oz #9's. Very uniform. Trulock customer service is fantastic and if you find that you dont like the pattern or the choke they will exchange it. I had an issue with the first choke I ordered from them, sent an email, the owner called me 30 min later and resolved the problem. Good folks.
